XBM3301 Li-ION/POLYMER 3-CELL PROTECTOR
GENERAL DESCRIPTION
XBM330x Series is a protection IC for 3 serial-cell lithium-ion / lithium polymer rechargeable
batteries and includes high accuracy voltage detection circuits 、 delay circuits and Cell
balance circuits。
XBM330x Series is suitable for protecting 3 serial-cell rechargeable lithium-ion / lithium
polymer battery packs from over-charge, over-discharge, over-current ， short-circuiting and
cell-unbalance.
