The BQ294712DSGR from Texas Instruments is an integrated circuit designed for overvoltage monitoring and protection in Li-Ion battery pack systems. It independently monitors each cell for overvoltage conditions and utilizes an external capacitor to program a delay timer before triggering the output. This device supports 2-, 3-, and 4-series cell configurations.
Key electrical characteristics include a factory-programmed overvoltage protection threshold ranging from 3.85 V to 4.6 V with high accuracy of ±10 mV. It exhibits low power consumption with a quiescent current of approximately 1 µA and low cell input leakage current of less than 100 nA. The output options are configurable as active high or open-drain active low.
Packaged in an 8-pin WSON with a 2.00 mm x 2.00 mm footprint, the BQ294712DSGR is suitable for space-constrained applications. It is designed for surface mount mounting. The operating temperature range is -40°C to 110°C.
Applications for this IC include notebook computers and UPS battery backup systems where reliable battery protection is critical.
