MAX77958
Standalone USB Type-C and USB Power
Delivery Controller
General Description
Benefits and Features
The MAX77958 is a robust solution for USB Type-C CC
detection and power delivery (PD) protocol implementation. It detects connected accessories or devices by using Type-C CC detection and USB PD messaging. The
IC protects against overvoltage and overcurrent, and detects moisture and prevents corrosion on the USB TypeC connector. The IC also has a D+/D- USB switch and
BC1.2 detection to support legacy USB standards. It contains VCONN switches for USB PD and an enable pin for
an external VCONN boost or buck converter. When the
USB PD negotiation is complete, the IC configures an alternate mode setting for external multiplexers.
● Supports Autonomous or MCU Based Configuration
• No Firmware Development Needed in Autonomous
Configuration
• Customizable Based on Application Requirements
The IC is compliant with USB Type-C Specification Release 1.3 and PD 3.0. It can be customized easily without
affecting the compliance.
The IC has an I2C master that can read and write to other
devices in the system so that its firmware can configure related devices without the main processor's assistance. For
example, it can configure an external charger based on
BC1.2 detection, CC detection, and PD communication.
The IC has an interrupt output pin to report event detection
and status changes. It also has an I2C interface that the
system can use to read/write and configure internal registers.
The IC has nine configurable GPIOs that can be used for
detection, as interrupts, and as the enable/disable pin for
external devices, or as ADC inputs.
The IC is available in a 3.10mm x 2.65mm, 0.5mm pitch,
wafer-level package (WLP).

MAX77958
Standalone USB Type-C and USB Power Delivery
Controller
Detailed Description
The MAX77958 is a robust solution for USB Type-C CC detection and power delivery (PD) protocol implementation.
It detects connected accessories or devices by using Type-C CC detection and USB PD messaging. The IC protects
against overvoltage and overcurrent, and detects moisture and prevents corrosion on the USB Type-C connector. The
IC also has a D+/D- USB switch and BC1.2 detection to support legacy USB standards. It contains VCONN switches for
USB PD and an enable pin for an external VCONN boost or buck converter.
The IC can be used in sink mode to determine the source capabilities of the connected device to optimize power into
the sink device. The IC can also be used in source mode to advertise the power capabilities of the source to connected
devices and accessories.
The IC is compliant with USB Type-C Version 1.3 and PD 3.0. It can be further customized without affecting the
compliance. The embedded default firmware in the MAX77958 is able to support operations that are expected in the
Type-C and PD applications.
The default firmware operations are as follows:
● BC1.2, Type-C, and PD adapter detection
● Automatic PD negotiation
● Default sink PDOs: 5V/3A, 9V/3A, and 15V/3A. If there are multiple source PDOs matching to the MAX77958 sink
PDO list, the MAX77958 requests the highest power of PDO.
● Automatic role setting according to port partner's role
In addition to the default operation, operation of the IC can be customized for specific applications. This is accomplished
using the customization script in the evaluation kit (EV kit) GUI to support different Maxim chargers.
The MAX77958 supports both standalone and MCU based systems. In the standalone system (see Figure 1), the
MAX77958 plays a role as system MCU along with the customization script that can be generated through the GUI SW.
The customization script is stored in the MTP. In response to events that are happening in the Type-C connector, the
customization script automatically executes commands specified by the designer. All sequential control operations are
possible without the need for MCU.

USB Type-C Interface and Control
The MAX77958 is a complete solution for USB port charger detection and High-Power USB charging on a single USB
Type-C connector. It can also be used in any power sink or source application.
The USB Type-C is an internal block that detects connected accessories by using USB Type-C, USB PD messaging
and USB BC1.2 charger detection. The USB Type-C block auto-configures switches for common connected accessories
including USB cables (SDP/CDP/DCP).
CC/USB PD Interface
The MAX77958 works as a Dual Role Port (DRP) compliant to USB Type-C Version 1.3. The USB Type-C functions
are controlled by a logic state machine which follows the USB Type-C requirements. There is support for the optional
Try.Sink function which places priority on the sink role. This creates the appearance of legacy operation when the device
is connected to another DRP. The IC automatically becomes a sink and draws power from the source. The IC firmware
can optionally set an external charger's input current limit based on the current advertised on the CC lines through the
master I2C interface.
USB Type-C Definitions

●
UFP—Upstream Facing Port. Typical USB device role for data transfer.
DFP—Down Stream Facing Port. Typical USB host role for data transfer.
DRP—Dual Role Port. USB Type-C port that can operate in either DFP or UFP roles.
Source—Initial power state for a DFP. Power role can be swapped by USB Power Delivery command.
Sink—Initial power state for a UFP. Power role can be swapped by USB Power Delivery command.
DRP
The USB Type-C connector management block supports DRP operation. The port cycles between advertising DFP/
source and UFP/sink operations while waiting for a port to be connected. The internal state machine handles all the

Standalone USB Type-C and USB Power Delivery
Controller
tasks of detecting and configuring the CC pins for the correct mode. A manual mode allows forcing either DFP or UFP
operation in cases where the DRP operation is not appropriate
Detecting Connected DFP
When a DFP is detected (either from DRP mode or force UFP mode), the USB Type-C Connection State Machine
detects the active CC line and reports this with an interrupt to the host application processor (AP). The AP then uses this
information to de-mux the SuperSpeed USB lines as required. The USB Type-C Connection State Machine also auto
detects the DFP advertised current (default, 1.5A and 3.0A). Upon detection of a change in the advertised current, an
interrupt is sent to the AP.
Detecting Connected UFP
When a UFP is detected (either from DRP mode or force DFP mode), the USB Type-C State Machine detects the active
CC line. If the Interrupt is enabled, and an AP is present, the IC toggles the INT line to report this to the host AP.
Additionally, if an active cable is connected, the IC detects the presence of RA on the unconnected CC line to determine
if it is necessary to turn on VCONN. The advertised initial supply current is the default USB current (500mA/900mA
depending on if SuperSpeed is active). The advertised current can be changed through an I2C command or automatically
to 1.5A. 3.0A is optionally available but is disabled by default.

Try.SNK Support
The MAX77958 operates as a DRP by default. This type of port can act as either a Power Sink/USB Data Peripheral or a
Power Source/USB Data Host. The USB Type-C logic state machine cycles between Source and Sink at a rate typically
around 75ms. This means that when the IC is connected to another device, which is also a DRP (for example, PC with a
C port), the source and sink roles are randomly assigned. The customer prefers that the mobile phone assumes the sink

connected to a standard DRP. If two devices with Try.SNK enable are connected, the role setting is again random.
Audio Accessory Mode Support
The IC detects an audio accessory device when both the CC1 and CC2 pins are pulled down to ground by an RA resistor
from the connected device.
DebugAcessory.SRC Support
The IC detects a connection to a debug and test system (DTS) when it operates in source power role. A debug accessory
device is detected when the CC1 and CC2 pins are pulled down to ground by an RD resistor from the connected device.
DebugAcessory.SNK Support
The IC detects a connection to a DTS when it operates in sink power role. A debug accessory device is detected when
the CC1 and CC2 pins are pulled up by an Rp resistor from the connected device.
The voltage levels on the CC1 and CC2 pins give the orientation and current capability.

Moisture Detection
The MAX77958 features Moisture and Dry detection on the USB Type-C receptacle. When the Moisture detection
feature is enabled (enabled as default), the MAX77958 is monitoring CC1/CC2 and SBU1/SBU2 for 1 DRP source cycle
periodically. In case the impedance on these pins are less than Moisture threshold, the MAX77958 runs its unique
algorithm until Dry is detected on the receptacle.
When Moisture and Dry are detected, the MAX77958 reports to the AP by setting CC_STATUS1[1].
To take advantage of the MAX77958 Moisture detection feature, external resistor configuration on the SBU1 and SBU2
are required.

USB BC1.2 D+/D- Adapter Detection
Description
The USB adapter detection is USB BC1.2 compliant with the ability to automatically detect common charger types.
USB adapter detection has the following controls in the I2C register file:
● Charger detection enable (ChgDetEn)
● Charger detection manual—request a new run of charger detection (ChgDetMan)
The Adapter Detection State Machine follows USB BC1.2 requirements and detects SDP, CDP, and DCP types. If the
D+/D- lines are detected as open, the adapter detection state machine indicates SDP as required by BC1.2 requirements.
With a USB BC1.2 compliant state machine, the IC reports that a DCP is detected based on the bias voltage. The IC
default firmware can automatically set an external charger's input current limit based on the BC1.2 adapter type that was
detected.
The IC also reports the operation status of the Adapter Detection State Machine in the ChgTypRun interrupt bit in the I2C
register map.

VCONN Switch
Description
The MAX77958 integrates the VCONN switch which connects VCIN to one of CC1 and CC2. Once CC detection identifies
Ra/Ra on CC1 and CC2, the VCONN switch routes VCIN to the pin that is not connected to the CC line in the cable.
The MAX77958 also provides programmable VCONN switch current limit from 200mA to 500mA in 100mA step. If VCONN
load current exceeds the current limit for 3ms, then an interrupt is generated to the Application Processor (AP). If AP
wants to keep supplying VCONN power, then the AP must configure a higher current limit or no current limit within 12ms.
If not, the VCONN switch is turned OFF in 12ms after an Interrupt is generated.

USB Power Delivery
Description
The IC supports USB Power Delivery Revision 3.0. The power delivery subsystem is separated into 2 parts: Automatic
Power Control and Application Processor Message Passthrough.
Application Processor Message Passthrough
There are many USB PD messages that are unrelated to power control. These messages pass on to the AP to decode
and reply. USB PD messages have time critical components and the IC automatically handles these time critical events.
IC Wakeup events
The IC automatically operates in the lowest possible power state. The IC power consumption depends on the following
conditions:
● Request has been made across the I2C bus
● USB Type-C end-to-end detection is valid
● VBUS is present
The lowest possible power consumption state is no VBUS, CCDetEn = 0, and no I2C traffic requests.

System Faults
The IC monitors the system for the following faults:
● Undervoltage lockout
● VIO fault
Undervoltage Lockout
When the VAVL falls below AVLUVLOF (2.6V max) for more than 8ms, the MAX77958 enters into a shutdown state. Once
the VAVL voltage is higher than AVLUVLOR (2.8V max), the MAX77958 exits shutdown state to be functional.
VIO Fault
When VIO1 and VIO2 fall below 1.0V, the IC goes into shutdown state. Once VIO1 and VIO2 voltages rise higher than
1.3V, the IC comes out of shutdown state.

The IC has different levels of reset as follows:
● Type S: Registers are reset each time when VDD1P8 < VDD_OKF
● Type O: Registers are reset each time when VDD1P8 < VDD_OKF or when the software reset command is
transmitted (SW_RESET = 0x0F)
WDT Reset
1. Firmware restarts a watchdog timer in 1.86s.
2. If the watchdog timer is not kicked in 1.86s, it executes the following actions:
a.) MAX77958 reboots
b.) MAX77958 notifies MA_SYSERROR_BOOT_WDT
I2C Serial Interface
The I2C serial bus consists of a bidirectional serial-data line (SDA) and a serial clock (SCL). I2C is an open-drain
bus. SDA and SCL require pullup resistors (500Ω or greater). Optional 24Ω resistors in series with SDA and SCL help
to protect the device inputs from high voltage spikes on the bus lines. Series resistors also minimize crosstalk and
undershoot on bus lines.
System Configuration
The I2C bus is a multi-master bus. The maximum number of devices that can attach to the bus is only limited by bus
capacitance.
Figure 6 shows an example of a typical I2C system. A device on the I2C bus that sends data to the bus is called a
transmitter. A device that receives data from the bus is called a receiver. The device that initiates a data transfer and
generates SCL clock signals to control the data transfer is a master. Any device that is being addressed by the master is
considered a slave. When the MAX77958 I2C-compatible interface is operating, it is a slave on the I2C bus and it can be
both a transmitter and a receiver.

Bit Transfer
One data bit is transferred for each SCL clock cycle. The data on SDA must remain stable during the high portion of the
SCL clock pulse. Changes in SDA while SCL is high are control signals (START and STOP conditions).

Figure 7. I2C Bit Transfer
START and STOP Conditions
When the I2C serial interface is inactive, SDA and SCL idle high. A master device initiates communication by issuing a
START condition. A START condition is a high-to-low transition on SDA with SCL high. A STOP condition is a low-to-high
transition on SDA, while SCL is high.
A START condition from the master signals the beginning of a transmission to the IC. The master terminates transmission
by issuing a NOT ACKNOWLEDGE followed by a STOP condition.
A STOP condition frees the bus. To issue a series of commands to the slave, the master can issue REPEATED START
(Sr) commands instead of a STOP command in order to maintain control of the bus. In general, a REPEATED START
command is functionally equivalent to a regular START command.
When a STOP condition or incorrect address is detected, the IC internally disconnects SCL from the I2C serial interface
until the next START condition, minimizing digital noise and feed-through.

Acknowledge
Both the I2C bus master and the IC (slave) generate acknowledge bits when receiving data. The acknowledge bit is the
last bit of each nine bit data packet. To generate an ACKNOWLEDGE (A), the receiving device must pull SDA low before
the rising edge of the acknowledge-related clock pulse (ninth pulse) and keep it low during the high period of the clock
pulse. To generate a NOT-ACKNOWLEDGE (nA), the receiving device allows SDA to be pulled high before the rising
edge of the acknowledge-related clock pulse and leaves it high during the high period of the clock pulse.
Monitoring the acknowledge bits allows for detection of unsuccessful data transfers. An unsuccessful data transfer occurs
if a receiving device is busy or if a system fault has occurred. In the event of an unsuccessful data transfer, the bus
master should reattempt communication at a later time.
Slave Address
The IC acts as a slave transmitter/receiver. The slave address of the IC is 0x4Ah/0x4Bh,0x4Ch/0x4Dh and 0x4Eh/0x4Fh
depending on configuration of GPIO6.The least significant bit is the read/write indicator (1 for read, 0 for write).

Clock Stretching
In general, the clock signal generation for I2C bus is the responsibility of the master device. I2C specification allows slow
slave devices to alter the clock signal by holding down the clock line. The process in which a slave device holds down
the clock line is typically called clock stretching. The IC does not use any form of clock stretching to hold down the clock
line.
General Call Address
The IC does not implement an I2C specification general call address. If the IC sees general call address (00000000b), it
does not issue an ACKNOWLEDGE (A).
Communication Speed
The IC provides I2C 3.0-compatible (1MHz) serial interface.
● I2C Revision 3 Compatible Serial Communications Channel
• 0Hz to 100kHz (Standard Mode)
• 0Hz to 400kHz (Fast Mode)
• 0Hz to 1MHz (Fast-Mode Plus)
● Does not Support I2C Clock Stretching
Operating in standard mode, fast mode, and fast-mode plus does not require any special protocols. The main
consideration when changing the bus speed through this range is the combination of the bus capacitance and pullup
resistors. Higher time constants created by the bus capacitance and pullup resistance (C x R) slow the bus operation.
Therefore, when increasing bus speeds the pullup resistance must be decreased to maintain a reasonable time constant.
Refer to the “Pullup Resistor Sizing” section of the I2C revision 3.0 specification for detailed guidance on the pullup
resistor selection. In general, for bus capacitance of 200pF, a 100kHz bus needs 5.6kΩ pullup resistors, a 400kHz bus
needs about 1.5kΩ pullup resistors, and a 1MHz bus needs 680Ω pullup resistors. Note that the pullup resistor dissipates
power when the open-drain bus is low. The lower the value of the pullup resistor, the higher the power dissipation (V2/R).

Standalone USB Type-C and USB Power Delivery
Controller
Operating in high-speed mode requires some special considerations. For the full list of considerations, see the I2C 3.0
specification. The major considerations with respect to the IC are:
● I2C bus master uses current source pullups to shorten the signal rise times.
● I2C slave must use a different set of input filters on its SDA and SCL lines to accommodate for the higher bus speed.
● The communication protocols need to utilize the high-speed master code.
At power-up and after each STOP condition, the IC input filters are set for standard mode, fast mode, or fast-mode plus
(i.e., 0Hz to 1MHz). To switch the input filters for high-speed mode, use the high-speed master code protocols that are
described in the Communication Protocols section.
Communication Protocols
The IC supports both writing and reading from its registers.
Writing to a Single Register
Figure 9 shows the protocol for the I2C master device to write one byte of data to the IC. This protocol is the same as
SMBus specification’s “Write Byte” protocol.
The “Write Byte” protocol is as follows:
1.
2.
3.
4.
5.
6.
7.
The master sends a START command (S).
The master sends the 7-bit slave address followed by a write bit (R/W = 0).
The addressed slave asserts an ACKNOWLEDGE (A) by pulling SDA low.
The master sends an 8-bit register pointer.
The slave acknowledges the register pointer.
The master sends a data byte.
The slave acknowledges the data byte. At the rising edge of SCL, the data byte is loaded into its target register and
the data becomes active.
8. The master sends a STOP condition (P) or a REPEATED START condition (Sr). Issuing a P ensures that the bus
input filters are set for 1MHz or slower operation. Issuing a REPEATED START (Sr) leaves the bus input filters in
their current state.

Writing to Sequential Registers
Figure 10 shows the protocol for writing to sequential registers. This protocol is similar to the “Write Byte” protocol, except
the master continues to write after it receives the first byte of data. When the master is done writing, it issues a STOP or
REPEATED START.
The “Writing to Sequential Registers” protocol is as follows:
1.
2.
3.
4.
5.
6.
7.
The master sends a START command (S).
The master sends the 7-bit slave address followed by a write bit (R/W = 0).
The addressed slave asserts an ACKNOWLEDGE (A) by pulling SDA low.
The master sends an 8-bit register pointer.
The slave acknowledges the register pointer.
The master sends a data byte.
The slave acknowledges the data byte. At the rising edge of SCL, the data byte is loaded into its target register and
the data becomes active.
8. Steps 6 to 7 are repeated as many times as the master requires.
9. During the last acknowledge related clock pulse, the slave issues an ACKNOWLEDGE (A).
10. The master sends a STOP condition (P) or a REPEATED START condition (Sr). Issuing a P ensures that the bus
input filters are set for 1MHz or slower operation. Issuing a REPEATED START (Sr) leaves the bus input filters in
their current state.

The MAX77958 I2C supports the HS mode extension feature. The HS extension feature keeps the high-speed operation
even after a ‘STOP’ condition. This eliminates the need for HS master code issued by the I2C master controller when the
I2C master controller wants to stay in HS mode for multiple read/write cycles.
As shown in Figure 14, the HS extension mode can be enabled by setting HS_EXT bit in I2C_CFG register (ADDR 0x15)
from LS mode only (entering HS extension mode from HS mode is not supported).

DESCRIPTION

All configuration and control commands to the USBC are sent and received
as a packet using an opcode to identify the packet.
A. Messages sent to the USBC
• 0x21—Opcode sent to USBC.
• 0x22 to 0x41—Message sent to USBC.
• Message size can be as short as 1 byte (Opcode only) and up to 33 bytes
(Opcode plus 32 bytes). But all messages must write to all bytes even if the
rest of the message is stuffed with 0s.
• Registers 0x21 to 0x41 act as a scratch pad for writing the message to the
USBC. The message is latched in when a value is written to register 0x41.
• All messages are acknowledged by the USBC by sending and generating an
interrupt.
• Data written to 0x21 to 0x41 is not auto cleared—the data remains in the
registers until the application processor overwrites it with a new message.
B. Messages received from USBC
• 0x51—Opcode identifying the message type.
• 0x52 to 0x71—Message sent to application processor.
• Message size can be as short as 1 byte (Opcode only) and up to 33 bytes
(Opcode plus 32 bytes).
• Data written to 0x51 to 0x71 is not auto cleared—the data remains in the
registers until the USBC overwrites them with a new message.

Applications Information
D+/D- USB 2.0 Switch Control
The integrated D+/D- switches in the MAX77958 are automatically configured by BC1.2 detection results.

MAX77958
MAX77958C/D
BC1.2 DETECTION RESULTS

D+/D- SWITCH CONFIGURATION
OPEN
SDP and CDP
CLOSED
DCP
OPEN
The configured D+/D- switch based on the BC1.2 detection result can be overridden by the AP through OP-Command
0x05. Refer to the User Guide for more information.
HVDCP Configuration
The MAX77958 supports adjustable high voltage adaptor (HVDCP) configuration, and the device provides D+/D- manual
control. To control D+/D-, OP-Command 0x03 should be set by AP. Refer to the User Guide for more information.
Push-Button Function
The MAX77958C/D supports the Push-Button function with GPIO7. When the Push-Button function is enabled by AP
or MCU, the GPIO7 pin starts the monitoring status. When a Falling Edge or Rising Edge transition is detected, the
MAX77958C/D interrupts AP through ACTION_INT[1]=1. See the Ordering Information table and the OP-Command 0x64
in the User Guide for more information.
External Interrupt
The MAX77958C/D supports an external interrupt function with GPIO8. This is useful when an external device such as
a companion charger needs to interrupt the MAX77958C/D to perform an operation specified by the application. When
the external interrupt function is enabled by AP or MCU, the GPIO8 pin starts the monitoring interrupt request. When the
interrupt request is detected, the MAX77958C/D sets the register ACTION_INT[0]=1. See the Ordering Information table
and the OP-Command 0x64 in the User Guide for more information.
MAX77958 IC Firmware Update with Dongle Board
The MAX77958C/D provides a firmware update capability through the dongle board. To update firmware through the
dongle board, the dongle board and evaluation kit GUI are required. Refer to the User Guide for more information.
FW Recovery Function
The MAX79758D features a FW recovery function. When the FW update fails, the FW version reads as FF.00, and it can
be recovered as ROM FW 58.03.
To retrieve production FW, the AP requires the following:
Case 1: The FW update fails while the AP is updating (battery is a power source in the system)
1) The AP sends an Op command: 0xDF 0xDA 0xA5 0xAD 0xC3 or Plug TA (apply VBUS)
Case 2: The FW update fails due to a dead battery event
1) Insert TA to provide VBUS for the system to power-up
2) The AP sends an Op command: 0xDF 0xDA 0xA5 0xAD 0xC3
The FW recovery Op command is only valid for the FW FF.00 case. Analog Devices provides a sample kernel driver to
achieve the FW recovery.

Typical Application Circuits
2/3-Cell Configurable Charger Application
Figure 15 illustrates a configurable charger application diagram using the MAX77958 and buck-boost charger devices.
In this application, the USB Type-C connector is used for SINK as well as SOURCE. The SINK role is automatically
active when the battery is charged using USB Type-C SOURCE that is connected to the USB Type-C connector in Figure
15. Based on the CC detection result, the SOURCE advertises its capability. The IC negotiates power contract with the
SOURCE connected to the USB Type-C connector. AP can choose appropriate SOURCE PDO and configure charging
current in the buck-boost charger accordingly.
The SOURCE role is active when SINK device is attached to the UBS Type-C connector as shown in Figure 15. The
IC becomes a power provider with the SOURCE role and advertises its capability to a device connected to USB Type-C
connector.

2/3-Cell Autonomous Charger Application
Figure 16 illustrates an autonomous charger application diagram using the MAX77958 and a buck-boost charger device.
In this application, the USB Type-C connector is used for SINK as well as SOURCE. The SINK role is automatically
active when the battery is charged using the USB Type-C SOURCE that is connected to the USB Type-C connector.
Based on the CC detection result, the SOURCE advertises its capability. The IC negotiates a power contract with the
SOURCE connected to the USB Type-C connector. The IC chooses an appropriate SOURCE PDO, and configures
charging current in the buck-boost charger accordingly through the master I2C interface in the IC.
The SOURCE role is active when a SINK device is attached to the USB Type-C connector as shown in Figure 16. The
IC becomes a power provider with the SOURCE role and advertises its capability to a device connected to USB Type-C
connector. In this scenario, the IC configures the buck-boost charger to reverse-buck mode to provide OTG voltage to
the device connected to the USB Type-C connector.

PD Power Adapter Application
Figure 18 illustrates an adapter application diagram using the MAX77958 device. In this application, the USB Type-C
connector is only used for SOURCE. The IC negotiates a power contract with the SINK connected to the USB TypeC connector. When SINK is attached, the IC advertises its SOURCE PDO to the SINK. Based on contracts, the IC
controls GPIOs to adjust VBUS that the SINK is requesting. When disconnection happens, the IC also controls GPIOs
to disconnect the power path on the VBUS path and discharges capacitors on the VBUS path to meet the USB Type-C
specification.
