    摘要： A monitor circuit for monitoring a level of a first and second regulated source may monitor a voltage level of regulated voltages or a current level of regulated currents. In an embodiment, the monitor circuit includes circuitry responsive to a first regulated voltage and to a second regulated voltage. A first circuit responsive to the first regulated voltage and to the second regulated voltage generates a first error signal indicative of at least one of an overvoltage condition of the first regulated voltage and an undervoltage condition of the second regulated voltage. A second circuit responsive to the first regulated voltage and to the second regulated voltage generates a second error signal indicative of at least one of an undervoltage condition of the first regulated voltage and an overvoltage condition of the second regulated voltage. A method for monitoring the levels of first and second regulated sources is also provided.

    摘要： A circuit includes a current source having at least first terminal and a second, control terminal. The current source is configured to receive a current control signal at the control terminal and in response thereto generates a first current signal at the first terminal. The current control signal controls a current level of the first current signal. The circuit also includes at least one sensing element responsive to one or more sense parameters and having an input adapted to couple to the first terminal of said current source. The sensing element is configured to receive one or more current signals comprising at least the first current signal and in response thereto generates a sensed output signal at an output thereof. A corresponding method for operating the circuit is also provided.
