BQ77905, BQ77904, 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
