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)
