Monolithic IC MM1491 Protection of Lithium Ion Battery (one cell)
■Outline
●This IC is a smaller, higher precision type of lithium ion battery protection IC as compared to the MM1301 series, and precision of ±25mV is guaranteed at 0℃ ~ 50℃.
●MM1301 had both VCC and VIN pins, but MM1491 has only the VCC pin.
■Features
●Overcharge detection voltage: Ta = 0 ~ +50℃ VCEL ± 25mV
●Overcharge detection dead time: CTD = 0.01μF 100 ms
●Consumption current (normal mode VCEL = 3.6V): 10μA typ.
●Consumption current (overdischarge mode VCEL = 1.9V): 0.05μA typ.
●Overcurrent detection reset conditions: Load open: between both ends of battery pack 50MΩ typ. load
