A method comprising:

• monitoring a magnitude of a first voltage supplied to power a circuit;
• based on the magnitude of the first voltage, controlling a magnitude of a second voltage applied to a first node of a first circuit component, the first node of the first circuit component coupled directly to a second circuit component, a second node of the first circuit component directly coupled to a first circuit path in the circuit, application of the second voltage to the first node of the first circuit component operative to control a state of the first circuit component sinking current received from the first circuit path through the first node of the first circuit component to a reference voltage node;
• wherein the first circuit component is a first switch;
• and
• wherein controlling the magnitude of the second voltage applied to the first node of the first circuit component includes:
• in response to detecting that the magnitude of the first voltage is below a threshold level, setting the magnitude of the second voltage to control the first switch to an ON-state.

An apparatus comprising:
