1BAT

This pin provides an accurate 4.2V output voltage and the charge current to the battery.

Only 2µA reverse current can flow in to the device when in Shutdown mode

2

POWER ON

Open Drain. When the STBC08 detects an undervoltage lockout condition or when the

external adaptor provide an input voltage higher than 7.2V or less than battery voltage,

POWER ON goes in high impedance state

3

CHRG

Open Drain. This pin goes in low impedance when the STBC08 is in precharge or charge

mode

4

GND

Ground pin

5PROG

Charge current program. Charge Current monitor and shutdown pin. The current
