Self-initiated control overcurrent protection circuit diagram
If the RS flip-flop reset still in the over-current condition, the level of FF1's Q-side is always high. It continues to cut off the device power supply. IC1 has been in the set state. The R side of FF1 does not work. The control circuit of the overcurrent devices can not only cut off the power and when it returns to be normal, it can start automatically. Thus the power interruption error which is generated by the phenomenon can be removed.
