This pin is multiplexed as CSN and NTC two functions:
1) CSN: current detect negative pin. In MTK PE+ 2.0/1.1 mode, this pin is connected
to the IC’s GND pin. A resistor of 10mOhm (1%) should be applied between IC’s
GND pin and USB port’s GND. In this condition, NTC function is disabled
automatically
2) NTC: temperature sensitive resistor detect pin. In NTC mode, this pin connect to
paralleled RNTC and R3 resistors to GND, MTK PE+ 2.0/1.1 function is disabled
automatically. The resistor of 10mOhm (1%) between IC’s GND and USB port’s
GND can be eliminated
When neither of these two functions are needed, CSN,CSP pins left floating, IC’s GND

11. Function Description
Charging Standards
IP2707 is a high-voltage, fast charging Physical Layer IC dedicated for charging applications where charging
standards required to be negotiated between USB ports. IP2707 is needed at the host-side, when the attached
portable client-side device negotiate the power allotment from the power source host-side, IP2707 can
auto-detect and respond to the those charging standards and may grant or deny the request based on the
available voltage/current. IP2707 will inform the power source host-side to adjust the output voltage by FB line
once charging request granted.
IP2707 support dual channel USB ports charging control, and DP1,DM1 support analysis several charging

standards, including HVDCP QC3.0/QC2.0 (Quick Charge) Class A, FCP (Hisilicon® Fast Charge Protocol), AFC
(Samsung® Adaptive Fast Charge), SFCP (Spreadtrum® Fast Charge Protocol), MTK PE+ 2.0/1.1 (MediaTek Pump
Express Plus 2.0/1.1), Apple® 2.4A, BC1.2 and Samsung® 2.0A. DP2, DM2 only support Apple 2.4A, Samsung 2.0A
and BC1.2.
IP2707 monitors the real-time voltage on DP line and DM line, when the attached device is not the fast
charging type, IP2707 will change the voltage on the DP, DM line to fulfill the negotiation process. When fast
charging client-side device connected, IP2707 auto-detect the type of charging standard and analysis the power
requirements, source/sink current on FB line to grant the request voltage. When the output voltage is default 5V,
FB line neither source nor sink current. IP2707 is not in control of the charging power loop, the actual charging
loop and charging current is determined by the host-side power source and the client-side USB port device.
IP2707 integrated USB Type-C DRP port controller, SEL2 can configure the Type-C device as DFP, UFP or DRP
mode. When worked as DFP mode, Type-C port support discharge to devices, at this moment CC1, CC2 will output
330uA current, for 3A maximum current capability broadcasting, IP2707 can work with Type-C UFP and DRP
devices. When worked as UFP, Type-C port only support charging from devices, at this moment, CC1, CC2 are
pulled down by 5.1kOhm resistor respectively, IP2707 can work with Type-C DFP, DRP devices. When worked as
DRP mode, Type-C port recognize the inserted device’s role and switch the pull-up or pull-down state on CC1 and
CC2, thus IP2707 can work with DFP, UFP and DRP devices. And as DRP mode, Try.SRC function will be enabled,
that is IP2707 work in DFP mode when connected with another DRP device.
SEL1
SEL1 line is used to configure the maximum voltage allotment that can be request, when SEL1 line is pull up
to high-voltage of VSELH, the IP2707 will not respond to any fast charging requirements and output default 5V;
When SEL1 line is floating, the maximum voltage allotment is 12V; When SEL1 line is pull down to GND, the
maximum voltage allotment is 20V.

IP2707 is configured as UFP device.

In Fast Charge Application
In fast charge application, after successful handshake as Type-C DFP role, ID1 will output high level voltage

In fast charge application, when worked as Type-C UFP, after VBUS is power ok, ID2 will output high level
voltage to turn on the PMOS and NMOS on the Type-C power rail, VBUS output from Type-C device go through
PMOS to VIN for the device to be charged, circuit for ID2 in fast charge application are recommended below:

VCC and VBUS
Both VCC and VBUS can power up IP2707, only when both VCC and VBUS are power ok, IP2707 work in
normal function. Only VCC power ok, IP2707 will go into low power mode, at this moment, DP1, DM1, DP2, DM2
function disabled and these pins are in high-z state, CC1 and CC2 still in work.
When worked as DRP device applied in power bank devices, to reduce the power consumption, IP2707 enters
low power mode when supplied by VCC only. Once VUBS power on or Type-C DFP mode is detected, IP2707 will
be wake up automatically and work in normal function.
When worked as DFP device applied in adaptors, there’s no low power mode, VCC can be floating, IP2707 can
work normally by ensuring VBUS power ok.
CC1 and CC2
When neither VBUS or VCC is power ok, CC1 and CC2 pin pulled down by 5.1kOhm resistor respectively.
If IP2707 worked as DRP mode applied in DRP devices (such as power bank, cell phone and tablets, etc), or

worked as UFP mode only, when neither VBUS or VCC are power ok, once Type-C port accessed device, IP2707
worked as UFP mode by default.
If IP2707 worked as DFP mode applied in DFP devices (such as adaptors, etc.), when neither VBUS or VCC are
power ok, to avoid the current back flow from Type-C DRP device into adaptors, switch devices are needed on the
CC1 and CC2 path, for isolating the pull down resistors on CC1 and CC2 of Type-C. Two NMOS switches (N5, N6)
should be added, circuit recommended below:
