The BQ77PL157APWR-4225 from Texas Instruments is a stackable secondary voltage protector for 3 to 6 series Li-Ion cells. This device provides precise overvoltage detection with preconfigured threshold limits, making it suitable for primary or secondary level voltage protection in Li-Ion battery packs.
Key features include a fixed 4.225 V overvoltage threshold with high accuracy (±20 mV MAX from 0°C to 50°C). It also boasts low power consumption, typically drawing only 2 µA to 2.5 µA in normal mode. The device can be stacked to monitor up to 18 series cells, offering design flexibility.
This IC is housed in a 16-pin TSSOP package, suitable for surface mount applications. Its operating temperature range is -40°C to 85°C. The BQ77PL157APWR-4225 is designed for applications such as power tools, UPS systems, e-bikes, scooters, medical devices, test equipment, and industrial products where reliable battery protection is critical.
Additional functionalities include programmable detection time delay and output activation for low-side FETs. It offers permanent or recoverable fault options for enhanced safety and reliability.
