Protection for Lithium-Ion Batteries

MM414x series are Li-ion battery protection IC and detect charge current / discharge current with high precision by current sensing resistor (Rsns). MM414x have two step discharge overcurrent detection. And system is protected appropriately in the next 2 state, Normal discharge mode and large curren 1) Range and accuracy of detection voltage\nOvercharge detection voltage 3.8V to 4.8V, 5mV steps Accuracy±15mV\nOverdischarge detection voltage 2.0V to 3.0V, 50mV steps Accuracy±35mV\nDischarging overcurrent detection voltage 1 +3mV to +50mV, 0.1mV steps Accuracy±1.00mV(MM4140 Series)\nAccuracy±0.75;
