The BQ77915 device is a low-power
battery pack protector that implements a suite of voltage, current, and temperature
protections and a smart cell balancing algorithm without microcontroller (MCU)
control. The device’s stackable interface provides simple scaling to support battery
cell applications from 3 series to 20 series or more. Protection thresholds and
delays are factory-programmed and available in a variety of configurations. Separate
overtemperature and undertemperature thresholds for discharge (OTD and UTD) and
charge (OTC and UTC)
provide
additional
flexibility.
