BQ77905 Stackable Lithium-Ion Battery Protector

The BQ77904 and BQ77905 devices are low-power battery pack protectors that implement a suite of voltage, current, and temperature protections without microcontroller (MCU) control. The device's stackable interface provides simple scaling to support battery cell applications from 3 series to 20 serie.

BQ77905 Features

* NORMAL mode: 6 µA (BQ77904 and BQ77905)

* Full suite of voltage, current, and temperature protections

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

* Voltage protection (accuracy ±10 mV)

* Overvoltage: 3 V to 4.575 V

* Undervoltage: 1.2 V
