Set Input Current Limit. This pin sets the input current limit directly. When IIN_EXT = low or high-Z, the
input limit is 100 mA. When IIN_EXT = high, the input limit is 500 mA.
Enable Trickle Charge Function. When TRK_EXT = low or high-Z, the trickle charge is enabled. When
TRK_EXT = high, the trickle charge is disabled.
Battery Pack Thermistor Connection. If not used, connect a dummy 10 kΩ resistor from THR to GND.
Battery Voltage Sense Pin.
Battery Okay Open-Drain Output Flag. Active low. This pin enables the system when the battery
reaches V
External Resistor Setting Pin for V_WEAK threshold. The use of this pin is optional. When not in use,
connect to GND.
