Claim 9:
10. The power switching system according to claim 1, wherein:
the transistor temperature sensor is a first transistor temperature sensor configured to measure a first transistor temperature of the power transistor, the switch module further including:
a second transistor temperature sensor configured to measure a second transistor temperature of the power transistor; and

the transistor temperature sense circuit is a first temperature sense circuit configured to receive the first transistor temperature from the first transistor temperature sensor and to output a first signal based on the first transistor temperature, the gate driver further including:
a second temperature sense circuit configured to receive the second transistor temperature from the second transistor temperature sensor and to output a second signal based on the second transistor temperature; and
a logic gate configured to receive the first signal and the second signal and to output the external fault signal, the external fault signal having a level corresponding to a thermal fault when either the first signal or the second signal has a level corresponding to a thermal fault in the power transistor.
