Detection of Lithium Ion Battery Overcharging MM1373
Detection of Lithium Ion Battery Overcharging
Monolithic IC MM1373
Outline
This IC detects overcharging of lithium ion batteries. It is designed for use with three or four battery cells, and
detects battery voltages for each cell. An overcharge detection delay time can be set using an external
capacitor. The overcharge detection signal output is open-collector, and goes low when overcharging is
detected.
