BQ7791501PWR General Description
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 devices 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.
