两串锂电保护芯片XBM3202高耐压带均衡功能

XBM3202 Series
Li-ion/Polymer 2-Cell Protector
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.
