description An electric power steering system for a vehicle includes a motor for providing assistance in turning the wheels of the vehicle. The motor is electrically connected to a controller. The controller includes a power device, such as a power transistor, electrically connected to the motor to variably provide electric power to the motor as needed. The controller also includes a gate drive device electrically connected to the power device for regulating operation the power device. A shutdown mechanism is electrically connected between the gate drive device and a power input. In the event of a fault, the shutdown mechanism isolates electrical power from the gate drive device. This prevents the power device from providing electric power to the power steering motor.
