BATTERY_VOLTAGE_MEASURING_REGULATOR

Published:2009/7/9 21:01:00 Author:May | From:SeekIC

This circuit allows a microprocessor system to measure its own battery voltage. A Texas Instrument 71431 precision shunt regulator acts as a precision reference and integrator/amplifier, measuring its own supply via voltage-dependent charge/discharge time intervals. Notice that you must write a short control and voltage calculation software routine for your system.
