Power switch short circuit protection

A power switch comprising short circuit protection circuitry, the power switch comprising:

• a cascode operable to provide a load with pulsed power from a power source, the cascode having a first transistor connected in series at an intermediate node to a second transistor;
• a gate driver that generates gate driver voltage pulses responsive to which a gate, of the first transistor is biased to turn the first transistor ON and OFF and provide pulsed power to the load;
• and
• short circuit protection circuitry comprising:
• a comparator connected to the second transistor via a high pass filter that receives voltage generated by current flowing through the second transistor and stray inductance of the second transistor and generates a comparator output signal that indicates when the received voltage filtered by the filter exceeds a threshold voltage;
• and
• voltage pulse control circuitry that controls the driver voltage pulses responsive to the comparator output signal.
