Abstract
A motor driving circuit for receiving a control signal to output at least one output current for driving a motor is provided. The motor driving circuit includes an input module, a gain module, an output module, a first slew rate limiting module, and a second slew rate limiting module. The first slew rate limiting module has a first limiting parameter. The second slew rate includes a second limiting parameter. An output current is outputted by the output terminal. When a rising slew rate of the output current is less than a first slew rate value, the first slew rate limiting module does not operate. When the rising slew rate of the output current is greater than the first slew rate value, the motor driving circuit limits the rising slew rate of the output current based on the first limiting parameter of the first slew rate limiting module.
