| MITSUMI Remaining Battery Power Display MM1305 Remaining Battery Power Display Monolithic IC MM1305 Outline This IC detects battery voltage and displays the power remaining in the battery. Portable equipment is becoming more and more popular, and one standard function of this type of equipment is remaining battery power display. This IC has four threshold voltages built in. Since their respective detection circuits share the reference voltage on one chip, the detection voltage for each lags in the same direction. Thus, there is much smaller error as compared to the reciprocal error resulting from combining single circuits. Also, the stepped display of remaining battery power as in nickel cadmium, nickel hydrogen and lithium ion batteries is enabled through super high precision voltage detection of 1%. Features 1. A separate line-up of detection voltages for alkaline magnesium and nickel cadmium and nickel hydrogen batteries. Alkaline magnesium : 1.350V /1.285V /1.200V /1.100V Nickel cadmium, nickel hydrogen : 1.275V /1.245V /1.205V /1.100V 2. Super high precision detection voltage : 1% typ. 3. Low current consumption : Waiting : 1.5A Detection : 12A 4. Ripple absorption pin Enables continuous ripple absorption and suppresses detection errors. 5.
