Abstract

A current sensing calibration method includes setting a first calibration current, inputting the first calibration current to a current sensing circuit for detecting a first real digital code, acquiring offset calibration data according to the first real digital code and a first ideal digital code corresponding to the first calibration current, setting a second calibration current and a third calibration current, inputting the second calibration current to the current sensing circuit for detecting a second real digital code, inputting the third calibration current to the current sensing circuit for detecting a third real digital code, acquiring gain calibration data according to the second real digital code, the third real digital code, a second ideal digital code, and a third ideal digital code, and acquiring channel temperature calibration data after the current sensing circuit is calibrated according to the offset calibration data and the gain calibration data.
