MITSUMI Charge and discharge control for coin-type lithium batteries and manganese dioxide lithium batteries MM1177
Charge and discharge control for coin-type lithium batteries and
manganese dioxide lithium batteries
Monolithic IC MM1177
Outline
This IC controls constant current charging and excess discharge for coin-shaped vanadium lithium batteries
and manganese dioxide batteries. It performs constant current charging, stops charging at set voltages, and
prevents excess discharging. When the voltage falls bellow a set level, it prohibits discharges and reduces IC
current consumption nearly to zero.
Features
During charging
1. Input voltage range
2. Current consumption (during constant current charging)
3. Current consumption (when charging is off)
4. Charging current
5. Charging shut-off voltage (Ta=-20~+70°C)
During discharging
1. Discharging shut-off voltage
2. Current consumption (IL-100µA, VBATT=3V)
3. Leak current during discharge shut-off
4. Voltage drop between battery and output (IL=100µA, VBATT=3V)
4.0~15.0V
