DUAL_VOLTAGE_COMPARATOR

Published:2009/7/12 20:50:00 Author:May | From:SeekIC

Use this dual comparator to monitor a battery while it's charging; the circuit will let you check for under- and overvoltage conditions.R3 and R4 set the trip levels at which the LEDs are activated. Almost any standard LEDs can be used. LED current is about 3 to 4 mA, as determined by the op-amp capability and resistors R1 and R2.
