Abstract
The present disclosure illustrates a motor drive circuit. The motor drive circuit includes a resistor module, a multiplexer, a data control unit, an analog-to-digital converter and a register. The resistor module receives an input voltage and generates at least one parameter voltage. The parameter voltage is associated with a motor speed curve of a motor. The multiplexer receives the parameter voltage. The data control unit controls the multiplexer to output the parameter voltage. The analog-to-digital converter receives the parameter voltage and converts the parameter voltage to digital form, and then outputs the digital parameter voltage to the data control unit. The register stores the digital parameter voltage outputted by the data control unit. A controller determines the motor speed curve according to the digital parameter voltage stored in the register, and drives the motor in response to the motor speed curve.
