两串锂电保护芯片XBM3201高耐压带均衡功能
Li-ION/POLYMER 2-CELL PROTECTOR
GENERAL DESCRIPTION
XBM3201 Series is a protection IC for 2 serial-cell lithium-ion / lithium polymer recharg
batteries and includes high accuracy voltage detection circuits 、 delay circuits and Cel
balance circuits。
XBM3201 Series is suitable for protecting 2 serial-cell rechargeable lithium-ion / lithium
polymer battery packs from over-charge, over-discharge, over-current , short-circuiting
cell-unbalance.
