MITSUMI Remaining Battery Power Display MM1210 www.DataSheet4U.com 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 Package SOP-8D (MM1210XF) Absolute Maximum Ratings Item Storage temperature Operating temperature Input voltage Output pin voltage Allowable loss Rating -40~+125°C -20~+70°C 5V 5V 300mW MITSUMI Remaining Battery Power Display MM1210 www.DataSheet4U.com Electrical Characteristics Item Current consumption (Unless otherwise specified Ta=25°C, VCC=1.5V, VCE=VCC) Symbol ICC1 ICC2 VTH1 VTH2 VT VH...
