Abstract
A circuit includes: a driver circuit; a sense resistor; a test circuit; a current sense circuit; a calibration controller; and a switch controller. The current sense circuit is configured to: obtain first sense signals responsive to a test voltage applied to the sense resistor by the test circuit, the test voltage being a direct-circuit voltage; and obtain second sense signals responsive a supply voltage applied to the sense resistor by the driver circuit, the supply voltage including a common-mode voltage. The calibration controller is configured to calibrate the current sense circuit responsive to the first sense signals and the second sense signals. The switch controller is configured to update switch control signals provided to the driver circuit responsive to current sense signals obtained by the calibrated current sense circuit.
