An electronic circuit is provided for protecting an electronic system and its power supply from damages caused by an over-current condition. The circuit automatically enters into a first state upon application of power from the power supply. In this first state, current is allowed to pass from the power supply through a channel to the electronic system. Upon detecting an over-current condition, a positive feedback will cause the circuit to enter into a second state, wherein the channel is cutoff.
