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 1.18V / 1.06V typ.

2. High precision detection voltages ±1 typ.

3. Low current consumption 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
