Abstract
A load control apparatus for controlling a power supply to an electrical load connected to an output terminal includes an overcurrent protection circuit having a power switch through which the electrical load receives a load current and a sensor component in series with the power switch that is configured to generate a voltage drop corresponding to the current rise speed of a load current from an input terminal to the output terminal. The protection circuit includes a driver circuit configured to detect an overcurrent depending on the voltage drop generated by the sensor component and/or at the power switch, and to switch off the power switch upon detection of an overcurrent within a switch-off period. The overcurrent protection circuit can include a power supply control circuit having a sensor component adapted to measure a supply voltage notified to a control unit of the load control apparatus adapted to control power supplied to the load.
