A method for monitoring a state of a switch is disclosed. The method includes
providing
a high side driver circuit in communication with a voltage source, activating the
high side driver circuit at a first predefined time interval, and sourcing voltage
to a resistor in communication with the high side driver circuit at the first predefined
time interval. Further, the method monitors the switch at the first predefined
time interval, and determines the state of the switch, and deactivates the high
side drive at a second predefined time interval.
