Abstract
Methods and apparatuses for detection of a presence of a load. A method may include, for example, applying and subsequently removing a supply voltage across the pair of nodes, comparing an electrical potential at one of the pair of nodes at a time after the supply voltage is removed with a reference value, and generating a signal having a value that depends upon an outcome of the comparison.
