BATTERY_SAVER_CIRCUIT

Published:2009/6/17 1:48:00 Author:May | From:SeekIC

This battery saver circuit can automatically turn off a small piece of test equipment after a desired period of time, allowing you to leave your shop worry free.This circuit uses a CD4011 IC to act as a simple timer. One section acts as an RC discharge timer (pin 7). This causes its output to go low, holding the three other outputs high acting as a 9-V source.After C1/R1 discharges approximately 10 minutes, the output drops to zero. S1 resets the circuit.
