DRV8803DW Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 50V, but it's recommended to keep it below 40V for reliable operation.
  • The current limit on the DRV8803DW can be adjusted by changing the value of the sense resistor (Rs) connected between the IS pin and ground. A smaller Rs value will result in a higher current limit.
  • The EN (enable) pin is used to enable or disable the 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 DRV8803DW from back-EMF when using inductive loads, a freewheeling diode (D1) should be connected in parallel with the load. This diode provides a path for the back-EMF current to flow when the driver is turned off.
  • The maximum switching frequency of the DRV8803DW is 100 kHz. However, the actual switching frequency may be limited by the load and the system's requirements.
