XM3202两串锂电保护芯片CPC8封装

XM3202两串锂电保护芯片

GENERAL DESCRIPTION

XBM3202 Series is a protection IC for 2 serial-cell lithium-ion / lithium polymer recharge

able batteries and includes high accuracy voltage detection circuits and delay circuits.

XBM3202 Series is suitable for protecting 2 serial-cell rechargeable lithium-ion / lithium

polymer battery packs from overcharge, over-discharge, overcurrent and short-circuiting.
