MM4129A中文资料Protection for Lithium-Ion Batteries数据手册MinebeaMitsumi规格书

描述 Description

The MM4128A / MM4129A series is a double protection IC for 2 cell Li batteries. It detects battery voltage for each cell. The configuration of delay time can be achieved. Output at the time of detection can be held for a fixed period of time; therefore, this can maintain a regular disconnection time of a fuse. In addition, high cell voltage can be dropped and then stopped at the level where battery deterioration does not occur by Electrical discharge function of the IC after disconnecting the fuse.
