  • Power transfer based stall detection techniques for stepper motor
    Patent number: 11777425
    Abstract: In accordance with at least one example of the description, a circuit is adapted to be coupled to a coil of a motor via an H-bridge circuit. The circuit includes a duty sensor, a subtractor, and a comparator. The duty sensor is coupled to the coil of the motor and is configured to provide raw run duty data responsive to a coil current through the coil. The subtractor is coupled to the duty sensor and is configured to provide a differential duty signal responsive to a stall duty signal and a run duty signal obtained using the raw run duty data. The comparator is coupled to the subtractor and is configured to provide a stall signal indicative of a stall condition for the motor responsive to the differential duty signal and a threshold value.
