STBC21FTR [STMicroelectronics]

The STBC21 is a constant current/constant voltage charger for single cell Li-Ion batteries. It features programmable charging parameters in NVM memory, with fast-charge current set by an external resistor up to 1.1 A. The device requires no external MOSFETs, sense resistors, or blocking diodes. It includes reverse current blocking, short-circuit protection, thermal shutdown, low standby current (<1 mA), reversed battery polarity protection, and an I²C interface for parameter programming. ESD protection is HBM ±2 kV and CDM 500 V on every pin. The package is HTSSOP-14 (5 x 4.4 mm) with an operative junction temperature range of -25°C to 125°C.
