Zusammenfassung:The utility model provides a short-circuit protection driving circuit and equipment, in the circuit, a first silicon carbide MOS module and a second silicon carbide MOS module are connected in series with a load main circuit to form a half-bridge circuit, and a current sensor S1 is connected with the load main circuit. The current sensor S1 is used for detecting a current signal between the first silicon carbide MOS module and the second silicon carbide MOS module in the load main circuit, the first driving circuit and the second driving circuit are both connected with the current sensor S1, and the first driving circuit is connected with the first silicon carbide MOS module. The first driving circuit is used for controlling the grid voltage of the first silicon carbide MOS module according to the current signal, the second driving circuit is connected with the second silicon carbide MOS module, and the second driving circuit is used for controlling the grid voltage of the second silicon carbide MOS module ac
