Remaining Battery Power Display MM1210
Remaining Battery Power Display
Monolithic IC MM1210 Series
Outline
This IC detects battery voltage and displays the remaining power in the battery using an LCD. Long life and
light weight are emphasized in the most recent portable equipment, which increasingly use nickel cadmium
and nickel hydrogen batteries. For these batteries, the discharge characteristics mean that extremely precise
detection of the remaining battery power is required.
This IC enables detection of this type through high precision voltage detection.
Features
1. Two built-in detection voltages
2. High precision detection voltages
3. Low current consumption
1.18V / 1.06V typ.
±1% typ.
During detection ; 15 μA typ.
During waiting ; 15 μA typ.
4. Setting possible during non-induction
It is possible to set a time period for which detection is ignored, as for example when voltage drops due to
temporary heavy loads.
5. Ripple absorption pins
It is possible to check fluctuations in detection through continuous rippling.
6. Built-in hysteresis voltage
