ABSTRACT:
A quadruple voltage regulator has four independently controllable power circuits in a single integrated circuit, and includes a current sensor for each of the power circuits. Each current sensor generates an active output signal when the magnitude of the current produced by the corresponding voltage regulator exceeds a selected limit. A single temperature sensing device monitors the temperature of the integrated circuit and generates a control signal when the temperature exceeds a selected threshold temperature magnitude. The output of the each current sensor is independently combined with the control signal from the temperature sensor to disable the corresponding voltage regulator circuit when the temperature exceeds the threshold magnitude coincident with an excess current produced by the regulator.
