Pin description
Pln N°
Symbol
Note
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
limitation is programmed using a 1% tolerance RPROG between PROG pin and GND
6VCC
Input supply voltage. The input range is from 4.25 to 6.5V. If VCC<VBAT+30mV the device
enters Shutdown mode and the sinked IBAT is less than 2µA
