DRV8812RHDT 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.
  • The current limit can be adjusted by changing the value of the sense resistor (Rs) connected to the CS pin. A smaller Rs value will increase the current limit, while a larger Rs value will decrease it.
  • 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. You can use this pin to control the motor driver using a microcontroller or other logic circuit.
  • You can add a freewheeling diode (D1) in parallel with the motor to protect the DRV8812RHDT from back-EMF. The diode should be rated for the maximum voltage and current of the motor.
  • The maximum operating frequency of the DRV8812RHDT is 100 kHz. However, the actual operating frequency may be limited by the motor and the application.
