www.DataSheet4U.com MITSUMI Protection of Lithium-Ion Batteries MM1412 Protection of Lithium-Ion Batteries Monolithic IC MM1412 Outline This IC protects lithium ion batteries in the event of overcharge, overdischarge and overcurrent. It has the following two functions: an overcurrent detection function that turns the external FET-SW off when a problem occurs during charging, etc. and excess voltage is impressed on each battery for longer than a certain time, and an overdischarge detection function that turns the external FET-SW off when battery voltage drops below a certain voltage during discharge, in order to prevent battery overdischarge. When these functions operate, the IC is put into low consumption current mode.
