The BQ296221DSGR from Texas Instruments is a high-accuracy, low-power overvoltage protection (OVP) IC for Li-ion battery pack applications. It is designed to monitor each cell in a 2-series to 4-series cell stack for overvoltage conditions.
Key features include factory-programmed OVP thresholds ranging from 3.85V to 4.6V with high accuracy of ±10mV. It incorporates a fixed internal delay timer that triggers the FET drive output upon detection of an overvoltage event. The device also provides a regulated supply output with options for 3.3V, 3.15V, or 3.0V, capable of delivering up to 2mA.
With very low power consumption, drawing approximately 4µA when all cells are below the protection threshold and as low as 1.2µA with the regulated output disabled, the BQ296221DSGR is suitable for power-sensitive applications. It also features low cell input leakage current of less than 100nA.
The IC is housed in a compact 8-pin WSON package with dimensions of 2mm x 2mm, making it ideal for space-constrained designs. It is available in both small and large tape and reel options.
