Abstract
A DC power control circuit with status report and protection against overloads and short circuits is provided in which the output stage comprises at least one output amplifier whose input receives an external control logic signal and whose output is connected, through a current limiter, to the output of the circuit. The control circuit further comprises a voltage threshold detector which compares the residue voltage of the output stage with a threshold voltage corresponding to a maximum acceptable difference and which delivers a report signal representative of the sign of the difference between the residue voltage and the threshold voltage.
