Description
D3, E3 SW1, SW2 I/O DC-to-DC Converter Inductor Connection. These pins are high current outputs when in charging mode.
D1, E1 VIN1, VIN2 I/O Power Connection to USB VBUS. These pins are high current inputs when in charging mode.
D4, E4 PGND1,
PGND2
G Charger Power Ground. These pins are high current inputs when in charging mode.
C2 AGND G Analog Ground.
E2 CFILT I/O 4.7 μF Filter Capacitor Connection. This pin is a high current input/output when in charging mode.
C3, C4 ISO_S1, ISO_S2 I/O Charger Supply Side Input to Internal Isolation FET/Battery Current Regulation FET.

A4 IIN_EXT I 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.
B2 TRK_EXT I 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.
A3

Battery Pack Thermistor Connection. If not used, connect a dummy 10 kΩ resistor from THR to GND.
C1 BAT_SNS I Battery Voltage Sense Pin.
D2 SYS_ON_OK O Battery Okay Open-Drain Output Flag. Active low. This pin enables the system when the battery
reaches V
WEAK
.
A1 V_WEAK_SET I/O External Resistor Setting Pin for V_WEAK threshold. The use of this pin is optional. When not in use,
connect to GND.
