... Protection for Lithium-Ion/Lithium Polymer Batteries (1 cell) MM3099/MM3199 Series MITSUMI Operation 1. Over charge detector (VD1) In the state of charging the battery, it will detect the overcharge state of the battery if the V voltage becomes higher than the overcharge detection voltage (4.275V typ.). And then the C turns to low level, so the external charging control Nch MOS FET turns OFF and it forbids to charge the battery ...
