Abstract

A wide current-and-voltage-range, precision supply circuit to conduct current (pulsed or continuous) having precisely-controlled current levels through a load is described. The supply circuit includes selectable current-sensing resistors in a feedback loop that controls current output to accommodate a wide range of currents provided to the load. The circuit can include a programmable output voltage that is applied to the load. The circuit can provide sensed voltage information from a single sensing node in the supply circuit to enable protection of the load and of power transistor(s) that conduct current through the load.
