  • Electrical load controller with fault detection
    Patent number: 9800042
    Abstract: A controller configured to detect fault conditions in a circuit that operates an electrical-load includes a gate-driver and a voltage-detector. The gate-driver is configured to control a gate-current to a switching-device. The gate-current is controlled such that the switching-device is operated in a linear-state when the switching-device transitions from an on-state to an off-state. The voltage-detector is configured to determine a voltage-drop across the switching-device. The controller is configured to indicate a no-fault condition when the voltage-drop is greater than a voltage-threshold for more time than a no-fault interval after the switching device is operated from the on-state to the linear-state.
