There are provided a protection circuit and a gate driving circuit for a semiconductor switching device. The protection circuit for a semiconductor switching device includes an overcurrent determining unit operated according to a gate signal to determine whether a load current flowing through the semiconductor switching device controlling the load current is an overcurrent, a load open determining unit determining whether a load is open, on the basis of a detection value from a current detection unit detecting the load current, and an error detection unit generating a fault signal when it is determined that the overcurrent flows and the load is open, while the gate signal is in a turned on level of the semiconductor switching device. |
