A gate driving circuit includes a gate control circuit and a gate voltage limit circuit. The gate control circuit establishes or breaks electrical continuity of a gate voltage supply path from a power source line to a gate terminal of a transistor in response to an on-command and an off-command. The gate voltage limit circuit limits a gate voltage of the transistor to be less than or equal to a first voltage in response to the on-command at least in a period until a determination of whether an electric current greater than a fault criterion value flows to the transistor ends and then limits the gate voltage to be less than or equal to a second voltage. |
