ABSTRACT:
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.
