Pin No.

Pin Name

Pin Function

FB3

Feedback Voltage Input of CH3.

Temperature Sense Input. The TS pin connects to a battery’s thermistor to

determine if the battery is too hot or too cold to charge. If the battery’s

temperature is out of range, charging is paused until it re-enters the valid range.

TS also detects whether the battery (with NTC) is present or not.

Power Output of 3.3V Buffer for Battery Temperature Sensing.

LX3

Switch Node of CH3.

PVD3

Power Input of CH3.

33, 34

BAT

Charger Output for Battery.

35, 36

SYS

Power Output for System. Connect this pin to System with a minimum 10

F

ceramic capacitor to GND.

VIN

Supply Voltage Input.

USB D+ Input for Charger Type Detection.

USB D- Input for Charger Type Detection.

VRTC

RTC LDO Power Output.

41 (Exposed pad)

GND

Power Ground. The exposed pad must be soldered to a large PCB and

connected to GND for maximum power dissipation.
