1. A switch health determination system, comprising:

  • a comparator coupled to a switch, the comparator configured to selectively compare a voltage on the switch to a first threshold voltage and a second threshold voltage, wherein the first and second threshold voltages have different values; and

    a controller coupled to the comparator, the controller configured to ascertain a first comparator state when the first threshold voltage is provided to the comparator and to ascertain a second comparator state when the second threshold voltage is provided to the comparator, the controller further configured to compare the first comparator state to the second comparator state and to determine a measure of health status of the switch based at least in part on the comparing of the first comparator state to the second comparator state.
