DRV8843PWPR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 40V, but it's recommended to keep it below 36V for reliable operation.
  • To configure the DRV8843PWPR for a unipolar stepper motor, connect the motor windings to the AOUT1 and AOUT2 pins for one phase, and BOUT1 and BOUT2 pins for the other phase. Set the MODE pin to logic high for unipolar mode.
  • The EN (enable) pin is used to enable or disable the motor driver. When EN is high, the driver is enabled, and when EN is low, the driver is disabled. Use the EN pin to control the motor's operation, such as during power-up or shutdown sequences.
  • The current limit on the DRV8843PWPR can be adjusted by connecting a resistor (RSENSE) between the SENSE pin and ground. The current limit is inversely proportional to the value of RSENSE. A smaller RSENSE value results in a higher current limit.
  • The nFAULT (fault) pin is an open-drain output that indicates a fault condition, such as overcurrent, undervoltage, or overtemperature. Connect a pull-up resistor to the nFAULT pin and monitor its state to detect fault conditions.
