Outline
MM3860 series are Li-ion battery protection IC and detect charge current / discharge current with high precision by current sensing
resistor (Rsns). MM3860 have two step discharge overcurrent detection. And system is protected appropriately in the next 2 state, Normal discharge mode and large current discharge mode.
Product Series
For one-cell
