wherein, when a base current at the base of the PNP transistor is at a level sufficient to cause the PNP transistor to be in a saturated ON state, the PNP transistor electrically couples the positive voltage input of the sensor power circuit to the sensor power connector,
wherein, during normal operation, current flowing through the second resistor into the emitter of the PNP transistor is below a nominal threshold current level, which causes a first bias voltage on the positive input of the push-pull comparator to be less than a second bias voltage on the negative input of the push-pull comparator, thereby causing a low-state voltage to appear at the output of the push-pull comparator,
wherein a first RC time constant exists as determined by the capacitance of the first capacitor and a total effective resistance at the base node of the PNP transistor,
wherein, when load current increases abruptly relative to the first RC time constant, such as would occur immediately following a short circuit across the sensor power connector,
voltage across the second resistor increases faster than voltage across the first capacitor decreases, resulting in an instantaneous net reduction of emitter-base voltage of the PNP transistor, and
the net reduction of the emitter-base voltage of the PNP transistor impedes the PNP transistor from delivering increased load current for a time period that is greater than the propagation delay from the inputs to the output of the push-pull comparator;
wherein, when load current demand exceeds the nominal threshold current level, such as would occur when a short circuit exists across the sensor power connector,

(2) the high-state voltage at the output of the push-pull comparator sources current into the first capacitor which reduces the base current available to the PNP transistor, and
(3) the reduced base current of the PNP transistor causes reduction of current into the emitter of the PNP transistor, thereby causing the current flowing through the second resistor to decrease to below the nominal threshold current level, thereby causing the first bias voltage on the positive input of the push-pull comparator to be less than the second bias voltage on the negative input of the push-pull comparator, thereby causing the low-state voltage to reappear at the output of the push-pull comparator,
wherein (1) (3) repeat at a first rate while the load current demand exceeds the nominal threshold current level.
