I just simply need to delay the signal to the Shut-down logic on the motor driver chip.
The motor driver only disables the mosfet outputs while the disable pin is held high (+5v logic).
So, what is happening now is that every time the comparator triggers an over current situation, the comparator triggers which sends a high signal to the driver chip (+5v) which shuts down the mosfets, but almost instantly once the mosfets are shut down, the over current situation is gone, and so the comparator see's the current load gone and drops the signal low again and the mosfets fire up. This basically repeats. But its so quick that its kind of like a jack hammer.
Over current
Shut down
Under current
start
repeat
That is what's happening at the moment.
So I am looking for a circuit that I can add, which once the comparator triggers (+5v 14ma), the timer circuit holds it at its +5V output for an adjustable amount of time (between 1 sec and 5-10sec) so the driver stays off rather than switching straight back on when the comparator senses the over current is gone!
I hope this is clearer, thanks
