ABSTRACT:
A current limiting circuit 12 is placed between a supply voltage, Vcc and circuitry 14. Current limiting circuit 12 supplies sufficient current for normal operation of circuitry 14, but less than would be required if all potentially conductive paths of circuitry 14 were active at one time. Current limiting circuit 12 may be operable to either limit or interrupt the flow of current between Vcc and circuitry 14 in response to a control signal. A second current limiting device 16 may be placed between circuitry 14 and a second supply voltage, VSS.
