Stresses beyond those listed under ‘Absolute Maximum Ratings’ may cause permanent damage to the device. These are stress

ratings only and functional operation of the device at these or any other conditions above those indicated in the operational

sections of the specifications is not implied. Exposure to Absolute Maximum Rating Conditions for extended periods may affect

device reliability.

Description

Function

1

VG

Internal Voltage Regulator. VG internally supplies power to gate driver,

connect a 100nF capacitor between VG pin and VCC pin.

2

PGND

Power Ground.

3

GND

Analog Ground.

4

CHRG

Open-Drain Output. When the battery is being charged, this pin is pulled low

by an internal switch. Otherwise this pin is in high impedance state.

5

DONE

Open-Drain Output. When the charging is terminated, this pin is pulled low

by an internal switch. Otherwise this pin is in high impedance state.
