Protection of Lithium Ion Battery (one cell) MM1491
Protection of Lithium Ion Battery (one cell)
Monolithic IC MM1491
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°C ~ 50°C. MM1301 had both VCC and VIN pins, but MM1491 has only the VCC pin.
