Description:

3/4/5 Cell Battery Protectors

Features

* (1) High-accuracy voltage detection for each cell
* overcharge threshold 3.6V~4.6V accuracy: ±25 mV (+25℃) accuracy: ±40 mV (-40℃ to +85℃)
* overcharge hysteresis 0.1V accuracy: ±50 mV
* over-discharge threshold 1.6V~3.0V accuracy: ±80 mV
* over-discharge hysteresis 0V / 0.2

Applications

* The BM3451 works constantly to monitor each cell’s voltage, the current of charge or discharge, and the temperature of the environment to provide overcharge, over-discharge, discharge overcurrent, short circuit, charge overcurrent and over-temperature protections, etc. Besides, it also can change t
