MM1251 Datasheet Remaining Battery Power Display

Manufacturer: MITSUMI ELECTRIC

Overview: MITSUMI Remaining Battery Power Display MM1251, MM1252, MM1253 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.
