The USB Type-C Current mechanism allows the DFP to offer more current than defined by the USB BC 1.2 Specification. Additionally, IP2712 integrate QC3.0/2.0 Quick charge output Protocol, include BC1.2/APPLE/SAMSUNG charging protocol, Support MTK PE+ Fast charging technology. 5.3 USB Power Delivery Controller The USB Power Delivery (PD) controller provides the physical layer (PHY) functionality of the USB-PD protocol. It is comprised of the following: - Mode Configuration for Source (Host), Sink (Device), or Source-Sink - Physical Layer (PHY) Protocol - Policy Engine Physical Layer (PHY) Functions The USB PD Physical Layer consists of a pair of transmitters and receivers that communicate across a single signal V1.04 Email: service@injoinic.com 11 / 21 Copyright © 2017, Injoinic Corp. IP2712 wire (CC). All communication is half duplex. The PHY Layer practices collision avoidance to minimize communication errors on the channel. The transmitter performs the following functions: - Receive packet data from the protocol layer - Calculate and append a CRC - Encode the packet data including the CRC (i.e. the payload) - Transmit the Packet (Preamble, SOP*, payload, CRC and EOP) across the channel using Bi-Phase Mark Coding (BMC) over CC The receiver performs the following functions: - Recover the clock and lock onto the Packet from the Preamble - Detect the SOP* - Decode the received data including the CRC - Detect the EOP and validate the CRC ·If the CRC is valid, deliver the packet data to the protocol layer. ·If the CRC is not valid, flush the received data. Policy Engine Policy Engine interacts with the Device Policy Manager in order to implement the present Local Policy. 5.4 Detecting a Valid DFP-to-UFP Connection For the USB TYPE-C solution, two pins on the connector, CC1 and CC2, are used to establish and manage the DFP-to-UFP connection. Functionally, the configuration channel is used to serve the following purposes. - DFP-to-UFP attach/detach detection - Plug orientation/cable twist detection - Initial DFP-to-UFP (host-to-device) and power relationships detection - USB Type-C VBUS current detection and usage - USB PD communication - Configure VCONN - Discover and configure optional Alternate and Accessory modes The general concept for setting up a valid connection between a DFP and UFP is based on being able to detect terminations residing in the product being attached. To aid in defining the functional behavior of CC, a pull-up (Rp) and pull-down (Rd) termination model is used – actual implementation in hosts and devices may vary, for example, the pull-up termination could be replaced by a current source.

When in a disconnected state, the IP2712 monitors the voltages on these pins to determine what is connected.

When the system with a dead battery has sufficient charge, it may use the USB PD DR_Swap message to become the DFP. 5.5 USB Type-C Current The USB Type-C connector uses CC pins for configuration including the ability for a Source to advertise to its port partner (Sink) the amount of current it can apply: - Default values defined by the USB Specification (500 mA for USB 2.0 ports, 900 mA for USB 3.1 ports) - 1.5A - 3.0A A Sink that takes advantage of the additional current offered shall monitor the CC pins and shall adjust its current consumption to remain within the value advertised by the Source. While a USB PD contract is in place, a Sink is not required to monitor USB Type-C current advertisements and shall not respond to USB Type-C current advertisements. The Source adjusts current source (or Rp) to advertise which of the three current levels it supports. (see Table 4) V1.04 Email: service@injoinic.com 14 / 21 Copyright © 2017, Injoinic Corp. IP2712 Table 4 Source CC Termination (Rp) Requirements Table 5, Table 6 and Table 7 provide the CC voltage values that a Source shall use to detect what is attached base on what is attached based on the USB Type-C Current advertisement that the Source is offering.

Application Information 6.1 Support E-MARK Cable IP2712 supports EMARK cable Function through VCON5V configuration. When VCON5V = 5V, IP2712 is automatically configured to support E-MARK cable. If the E-MARK cable support a maximum current of 5A, the maximum output power can be configured as 100W. When VCON5V < 5V, IP2712 can’t support E-MARK cable, the maximum output power can be configured as 60W. 6.2 Use PLIM to set the Source Power Limit The IP2712 checks the voltage at PLIM to set the power limit. When VCON5V < 5V, the IP2712 can’t support E-MARK cable. The voltage step of power limit is 40mV/W. When the voltage at PLIM is greater than or equal to 2400mV, the power limit reaches the max power of 60W. When VCON5V = 5V, the IP2712 can support E-MARK cable. The voltage step of power limit is 20mV/W. When the voltage at PLIM is greater than or equal to 2000mV, the power limit reaches the max power of 100W. The power limit is used for different purpose. 1. The value of power limit is used to set the output current limit in real time. 2. The value of power limit is used to Change the Maximum Current of Source Capabilities Message. 6.3 Programmable Power Supply (PPS) The voltages and currents a Source supported is as define in Table 10.
