DRV8833RTYT datasheet by Texas Instruments

DRV8833RTYT Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the VM pin?
  The maximum voltage that can be applied to the VM pin is 15V, but it's recommended to keep it below 12V for optimal performance.
• How do I configure the DRV8833RTYT for a unipolar stepper motor?
  To configure the DRV8833RTYT for a unipolar stepper motor, connect the motor coils between the AOUT1 and AOUT2 pins, and the BOUT1 and BOUT2 pins. Then, set the MODE pin to logic high to enable unipolar mode.
• What is the purpose of the nSLEEP pin, and how do I use it?
  The nSLEEP pin is an active-low input that puts the device into a low-power sleep mode when driven low. To use it, connect the nSLEEP pin to a logic low signal when the motor is not in use to reduce power consumption.
• How do I adjust the current limit on the DRV8833RTYT?
  The current limit on the DRV8833RTYT can be adjusted by connecting a resistor between the ITRIM pin and the GND pin. The current limit is inversely proportional to the resistance value.
• What is the maximum current that the DRV8833RTYT can deliver?
  The DRV8833RTYT can deliver up to 2A of current per phase, making it suitable for small to medium-sized stepper motors.
