1. An apparatus comprising:
a switch that switches a load current from a high voltage source through a high voltage load, wherein the switch is controlled to turn off when a voltage at a voltage sense terminal exceeds a selected voltage level;
a diode coupled to the voltage sense terminal;
a capacitor coupled to the voltage sense terminal; and
a temperature sensing element coupled to the voltage sense terminal, wherein the temperature sensing element couples to the voltage sense terminal via a resistor.
