The STBC03 is a highly integrated power management, embedding a linear battery charger, a 150 mA LDO, 2 SPDT load switches, and a protection circuit module (PCM) to prevent the battery from being damaged under fault conditions. The STBC03 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 to 5% of the programmed fast charge current, but has fixed values for fast charge currents lower than 20 mA. The battery floating voltage value is programmable and can be set to a value up to 4.45 V. The STBC03 also features a charger enable input to stop the charging process anytime. The STBC03 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 STBC03 draws less than 10 nA from the connected battery in shipping mode conditions, so to maximize the battery life during shelf life of the final application. The device is available in the Flip Chip 30 package.
