The BQ7721605PWR is a 3-s to 16-s cell Li-ion battery management voltage and temperature protection device manufactured by Texas Instruments. Ideal for use in spacecrafts, industrial and consumer applications, it provides over-voltage, under-voltage, overtemperature, and over-temperature protection for Li-ion batteries. Additionally, this device features an internal delay timer, which provides a time delay of up to 2s between the interrupt and the actual cell voltage disconnect, avoids false tripping due to short power outages, and ensures a safe restart of the system. With its Ethernet, system management bus, low pin count, and dedicated interrupt pin, this device offers an efficient and reliable solution for Li-ion batteries.
