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.

6

TEMP

Battery Temperature Monitoring Input. Connect an NTC resistor from this pin

to GND.

7

EOC

End-of-Charge Current Setting Pin. Connect this pin to GND directly or via a

resistor.

8

COM 1

Loop Compensation Input 1. Connect a 470pF capacitor from this pin to

GND.

9

COM 2

Loop Compensation Input 2. Connect a 220nF capacitor in series with an

120Ω resistor from this pin to GND.

10

Test

Test pin. Connected this pin to GND.

11

COM 3

Loop Compensation Input 3. Connect an 100nF capacitor from this pin to

GND.
