Abstract

A circuit includes an input pin connected to an integrated circuit (IC) that receives an input voltage that is provided to a first voltage circuit within the IC. A pass device having a control input responds to a first control signal state and a second control signal state. The first control signal state turns the pass device off such that the input voltage is switched off to block the passing of the input voltage to a second voltage circuit within the IC. The second control signal state turns the pass device on such that the input voltage is switched through the pass device to the second voltage circuit in a voltage range that is compatible with an input operating voltage range of the second voltage circuit.
