description	An apparatus includes a blower drive and a protection circuit. The blower drive includes a processor and a capacitor. The capacitor is electrically coupled to the processor and provides electrical power to the processor during a short circuit in the blower drive. The protection circuit is electrically coupled to the blower drive and includes a first switch, a positive temperature coefficient resistor, and a second switch. The positive temperature coefficient resistor is electrically coupled in series to the first switch. The second switch is electrically coupled in parallel to the positive temperature coefficient resistor and opens during the short circuit in the blower drive. The first switch opens after the second switch opens and after a short circuit current is below a threshold.
