The BQ296215DSGR from Texas Instruments is a high-accuracy, low-power overvoltage protection IC designed for 2-series, 3-series, and 4-series cell Li-ion battery packs. It monitors each cell individually for overvoltage conditions and employs a fixed internal delay timer before triggering an output pin.
Key electrical specifications include a maximum input voltage of 20V and a typical operating current of 4µA when VCELL(ALL) is below the protection threshold, dropping to 1.2µA with the regulated output disabled. The overvoltage protection thresholds range from 3.85V to 4.6V with high accuracy of ±10mV. The device also provides regulated output options of 3.3V, 3.15V, and 3.0V.
This IC is housed in an 8-WSON (2x2 mm) surface-mount package, making it suitable for space-constrained applications. The operating temperature range is -40°C to 110°C.
Features include LDO output, single pin output drive, and undervoltage protection functionality. The low leakage current per cell input of less than 100nA contributes to its overall low power design.
