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
