Abstract
A power supply circuit includes a plurality of current supply circuits, each configured to provide an output current as a function of a respective digital control signal, and a measurement current proportional to the respective output current. A control circuit selects one of the measurement currents and one of the digital control signals associated with a current supply circuit. A comparison circuit generates a threshold current, and generates a comparison signal by comparing the selected measurement current with the threshold current. The control circuit sets, during a first phase, the threshold current to a first value smaller than an expected value for the selected measurement current as indicated by the selected digital control signal, and, during a second phase, to a second value greater than the expected value. The control circuit verifies whether the comparison signal is de-asserted during the first phase and asserted during the second phase.
