ABSTRACT:
A circuit for selectively regulating a current at one value from multiple defined values. The circuit includes a sense selector to select a current sense signal from multiple current sense signals and a current path selector to select a current pathway from multiple current pathways. Each current pathway is associated with a resistance value. The resistance value of the selected current pathway, in part, defines the value at which the output current is regulated to.
