MM3563中文资料1～3节锂离子／锂聚合物可充电电池用二级保护IC数据手册MinebeaMitsumi规格书

描述 Description

This IC are secondary protection IC using high voltage CMOS process for overcharge protection of the rechargeable Lithium-ion or Lithium-polymer battery. The high accuracy overcharge detection of each cell of the rechargeable 1-3-cell Lithium-ion or Lithium-polymer battery is possible. Each of these IC composed of four voltage detectors, reference voltage sources, oscillator, counter circuit and logical circuits.The ultra-small package SSON-6A is used to minimize footprints.
