BQ77915 Datasheet - Texas Instruments

BQ77915 3-Series to 5-Series Stackable Ultra-Low Power Primary Protector

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.

BQ77915 Features

* Ultra-low quiescent current: 8 µA typ. (NORMAL mode), 2 µA (HIBERNATE mode)

* Full suite of voltage, current, and temperature protections

* Smart passive cell balancing removes cell-to-cell imbalance

* Scalable cell count from 3 series to 20 series or more
