Zusammenfassung:	Systems, methods, and circuits for determining one or more switch statuses are disclosed herein. In one example embodiment, such a system includes a first port configured to be coupled to a switch, a capacitor, a comparator having first and second input ports and an output port, a current source coupled to the first input port, and a control component. The first input port is coupled to the first port and a threshold voltage if applied to the second input port. The control component is configured so that, in at least one circumstance, it causes the current source to cease driving the current in response to receiving an indication from the output port indicating that an additional voltage applied to the first input port has changed from being less than the threshold voltage to being greater than that voltage, the indication being indicative of the switch status.
