A drive device drives a power switching element (200) having a control electrode (210) for controlling the output current supplied to a load by the application of voltage. The drive device is provided with a control unit (10) for controlling the timing of the application of voltage to the control electrode. The control electrode has a plurality of divided electrodes. The plurality of divided electrodes includes a first electrode (211) and a second electrode (212). During a short-circuit detection period for detecting a short circuit of the load, the control unit drives the switching element in a safe mode in which voltage is applied to the first electrode or the second electrode, and during a normal drive period for normal driving of the load, the control unit drives the switching element in a normal mode in which voltage is applied at least to the divided electrode, among the first and second electrodes, to which voltage is not applied in safe mode. |
