STBC02JR Battery Management ICs by STMicroelectronics

Li-Ion linear battery charger with LDO, load switches and reset generator


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). The STBC02 draws less than 10 nA from the connected battery in shipping mode conditions, so to maximize the battery life during end product shelf life. The device is available in the Flip Chip 30 package.
