Motor driving circuit and motor driving device

A motor driving circuit comprising:

• a wiring pattern formed in a circuit board, the wiring pattern being configured such that electrical current flowing into a motor flows through the wiring pattern;
• a current measurement circuit configured to measure an amount of electrical current flowing through the wiring pattern, based on an amount of voltage drop caused by the electrical current flowing through the wiring pattern;
• a temperature measurement circuit configured to measure an ambient temperature of the wiring pattern;
• and
• a drive unit configured
• to adjust a current measurement value measured by the current measurement circuit, based on first adjustment data that compensates for variation in resistance of the wiring pattern caused by an individual difference in the circuit board, second adjustment data that compensates for variation in resistance of the wiring pattern caused by a temperature characteristic of the wiring pattern, and the temperature measured by the temperature measurement circuit, and
• to drive the motor based on an adjusted current value which is the adjusted current measurement value.
