Abstract
A sensor device coupled to a communication interface bus, the sensor device includes: a current source having a first terminal operable to receive a supply current, a second terminal operable to provide a supply current, and a control terminal, wherein an operating voltage is supplied by a current through the current source; a voltage clamp having a first terminal coupled to the second terminal of the current source, a second terminal coupled to a power supply terminal, and an output terminal operable to provide a current sense signal; and a control circuit having an input terminal coupled to the output terminal of the voltage clamp and an output terminal coupled to the control terminal of the current source operable to provide an adjustment signal responsive to the current sense signal, wherein the current source is configured to adjust the current through the current source responsive to the adjustment signal.
