DRV8834RGET datasheet by Texas Instruments

DRV8834RGET Frequently Asked Questions (FAQs)

• What is the maximum current rating of the DRV8834RGET?
  The maximum current rating of the DRV8834RGET is 1.5A per channel, with a peak current of 2.5A.
• How do I configure the DRV8834RGET for microstepping?
  To configure the DRV8834RGET for microstepping, you need to set the M0 and M1 pins to select the desired microstepping mode. The datasheet provides a table to determine the correct pin settings for 1/2, 1/4, 1/8, 1/16, and 1/32 microstepping.
• What is the purpose of the EN pin on the DRV8834RGET?
  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 and the motor coils are turned off.
• How do I protect the DRV8834RGET from overheating?
  To protect the DRV8834RGET from overheating, ensure good airflow around the device, use a heat sink if necessary, and monitor the device temperature using the THERM pin. You can also implement thermal protection in your system design.
• Can I use the DRV8834RGET with a stepper motor that requires a higher voltage than 2.5V?
  Yes, the DRV8834RGET can be used with stepper motors that require higher voltages. The device has an internal voltage regulator that can handle input voltages up to 35V, but the output voltage to the motor is limited to 2.5V. You can use an external voltage regulator to step down the input voltage to the required motor voltage.
