Abstract
A motor driver system. Implementations may include: a motor driver configured to couple with a motor where the motor driver comprises a multipurpose pin. A controller may be included coupled with the motor driver through at least the multipurpose pin. The motor driver during an enable mode, may be configured to receive serial data from the controller and to send serial data to the controller using the multipurpose pin during a normal operation mode of the motor driver. The motor driver may be configured to output a frequency generator (FG) signal to the controller using the multipurpose pin during the normal operation mode of the motor driver.
Claims20
A motor driver system, comprising:
- a motor driver configured to couple with a motor, the motor driver comprising a multipurpose pin;
- wherein the motor driver is configured to couple with a controller through at least the multipurpose pin;
- wherein the motor driver, during an enable mode, is configured to receive serial data from the controller and to send serial data to the controller using the multipurpose pin during a normal operation mode of the motor driver;
- and
- wherein the motor driver is configured to output a frequency generator (FG) signal to the controller using the multipurpose pin during the normal operation mode of the motor driver.
A motor driver comprising:
- a communication controller, an edge detector, an enable signal generator, a frequency generator logic unit, a selection signal generator, and a busy signal generator operatively coupled together and coupled with an inverter;
- and
- a multipurpose pin coupled with the inverter;
- wherein the motor driver is configured to couple with a controller through the multipurpose pin.
A method of driving a motor, the method, comprising:
- providing a motor driver configured to couple with a motor, the motor driver comprising a multipurpose pin, the multipurpose pin configured to couple a controller with the motor driver through at least the multipurpose pin;
- using the motor driver, receiving serial data from the controller using the multipurpose pin and sending serial data to the controller using the multipurpose pin during a normal operation mode of the motor driver, and
- outputting a frequency generator (FG) signal to the controller using the multipurpose pin during the normal operation mode of the motor driver.
