MD1421ExxCPAL中文资料Protection for Lithium-Ion Batteries数据手册MinebeaMitsumi规格书

描述 Description

The MD1421ExxCPAL series are protection IC with integrated MOSFET for protection of the rechargeable lithium-ion or lithium-polymer battery. The overcharge, overdischarge and discharging and charging overcurrent protection of the rechargeable one-cell lithium-ion or lithium-polymer battery can be detected.
