General Description /产品概述
The BM3560 is a professional protection IC for 6 cells rechargeable battery
pack; it is highly integrated,
high accuracy and generally used in high-and-mid end power tools, electric
bicycle and UPS applications.
The BM3560 works constantly to monitor each cell's voltage, the current of
charge or discharge, wire
breaking or not and the temperature of the environment to provide overcharge,
over-discharge, discharge
overcurrent, short circuit, charge overcurrent, breaking wire and temperature
protections, etc. Besides, it
also can change the protection delay time of over-discharge and discharge
overcurrent by setting the
external capacitors.
