Description

The STBC02 is a highly integrated power management, embedding a linear battery

charger, a 150 mA LDO, 2 SPDT load switches, a smart reset/watchdog block and

a protection circuit module (PCM) to prevent the battery from being damaged under

fault conditions.

The STBC02 uses a CC/CV algorithm to charge the battery; the fast charge and

the pre-charge current can be both independently programmed using dedicated

resistors. The termination current is set by default, being 5% of the programmed

fast charge current, but it can also be fixed to different values. Likewise, the battery

floating voltage value is programmable and can be set to a value up to 4.45 V.

The STBC02 also features a charger enable input to stop the charging process

anytime.

The STBC02 is automatically powered off from the connected battery when the IN pin

is not connected to a valid power source (battery mode).

A battery under/overtemperature condition can be detected by using an external

circuitry (NTC thermistor).
