MITSUMI

Remaining Battery Power Display

Monolithic IC MM1251, MM1252, MM1253

Outline

This IC detects battery voltage and displays the power remaining in the battery. Display of the battery's

remaining power is an indispensable function for portable equipment. The use of this IC makes this display

easily achievable.

The usual method of display of remaining battery power, as in the MM1206, is three marks lighting up in

sequence on an LED or other display. This IC, however, uses only one light to display the remaining battery

power, resulting in lower cost.

Features

1. Adjustable flashing speed

2. Adjustable detection voltage supports all settings

3. Adjustable hysteresis voltage enables response to large ripple settings

4. High precision voltage detection (MM1253) enables support of sets using nickel cadmium and other

batteries

5. The LED can be lit up by the voltage from one battery (type of special built-in step-up circuit : rank B)
