It integrates a 1\/256-step microstepping indexer for ultra-smooth motion profiles. The SPI serial interface configures output current (torque), step mode, decay mode, and stall detection parameters. Auto-mixed decay mode dynamically adjusts the current decay strategy for optimal performance across speed ranges. The stall detection feature uses back-EMF sensing to detect motor stall without external sensors, enabling sensorless homing. The internal 5V regulator can supply up to 10mA for external logic. Protection features include overcurrent protection (OCP), overtemperature shutdown (OTS), and undervoltage lockout (UVLO), with a dedicated FAULTn pin and individual fault status bits accessible via SPI.","working_principle":"The DRV8711DCPR operates as a microstepping chopper driver for external N-channel MOSFETs. The STEP\/DIR interface accepts step pulses from the MCU; the internal indexer converts each step into the appropriate phase current targets for the two motor windings based on the configured microstep resolution (full step to 1\/256). The SPI interface sets the target current via an 8-bit torque DAC and the current sense amplifier gain (5, 10, 20, or 40 V\/V) for external sense resistors. The PWM chopper regulates the winding current: when the current through the sense resistor exceeds the target, the driver turns off the high-side MOSFET for a programmable off-time (0.5\u00b5s to 128\u00b5s), allowing the current to decay through the low-side MOSFET and body diode. The decay mode (fast, slow, or auto-mixed) determines whether both low-side MOSFETs are on (slow decay) or only one (fast decay) during the off-time. Auto-mixed decay uses slow decay when the current is increasing and fast decay when decreasing, minimizing distortion. Stall detection monitors the back-EMF of the motor windings; when the motor stalls, the BEMF drops to near zero, which is detected and reported on the STALLn output and via SPI status bits. The overcurrent protection monitors the voltage across each external MOSFET; if the drop exceeds the programmable threshold (250mV to 1000mV), all outputs are disabled and the fault is latched.","pin_description":"\n
