This disclosure is directed to circuits for controlling voltage from a voltage source to one or more light emitting diodes. The circuit includes a first transistor comprising a power switch that is configured to define a load current path from the voltage source to the one or more light emitting diodes. The circuit also includes a second transistor, which can be controlled based on the light emitting diodes, wherein the second transistor is configured to turn off when one or more of the lights emitting diodes exhibit an electoral short. The first transistor is configured to turn off in response to the second transistor turning off so as to provide short circuit protection for the circuit.
