Abstract
A current limiting controller () for a light emitting diode (LED) driver automatically resets the LED driver to normal operation after elimination of a fault. The current limiting controller () includes a fault detector to detect a fault across a load () that is being driven by the driver circuit (); a current limiter () to limit the current supplied from the driver circuit () to the load () in response to the detected fault; and a reset circuit () to disable the current limiter () upon expiration of a first time interval after the fault is detected, and to allow the current limiter () again to limit the current supplied from the driver circuit () to the load () when the detected fault remains after a second time interval.
