Hi all,
I want to drive latching relay for a protection circuit. Reset coil of the relay needs 50ms and 250mA pulse signal for the reset operation. I will drive it with a comparator circuit using an opamp. But when a protection state occurs, comparator drives continuously the reset coil and the system wasting power unnecessarily. How to convert continous comparator ouput signal to a one shot (50ms) signal? After a reset condition, i will not set the relay anymore and the relay will remain in the reset state permanatly. Thanks for advices.
Best regards,
Bragas
