Abstract
A protection mode control circuit includes an auto-restart counter configured to count the cycle of a first signal in a protection condition and to generate an auto-restart signal when a result of the count reaches a protection reference value and a latch mode unit configured to generate a latch mode signal for changing protection mode to latch mode when the auto-restart signal is consecutively generated by a predetermined threshold number.
