DRV8812RHDR 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 on the DRV8812RHDR can be adjusted by changing the value of the sense resistor (Rs) connected to the CS pin. A smaller Rs value will result in a higher current limit.
  • 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. This pin can be used to implement a shutdown or standby mode in the system.
  • To protect the DRV8812RHDR from back-EMF, a freewheeling diode (D1) should be connected across the motor terminals. This diode allows the back-EMF to be safely dissipated.
  • The maximum operating frequency of the DRV8812RHDR is 100 kHz. However, the actual operating frequency may be limited by the motor and system requirements.
