DRV8804DW 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 sense resistor value can be calculated using the formula: RSENSE = (VCS x RATIO) / (ICS x GAIN), where VCS is the current sense voltage, RATIO is the current sense ratio, ICS is the maximum current, and GAIN is the gain of the current sense amplifier.
  • The EN pin is an enable input that allows the device to be enabled or disabled. When EN is high, the device is enabled, and when EN is low, the device is disabled. This pin can be used to implement a shutdown or standby mode in the system.
  • The DRV8804DW can be configured for half-bridge or full-bridge operation by connecting the appropriate pins. For half-bridge operation, connect the HB pin to VCC, and for full-bridge operation, connect the HB pin to GND.
  • The dead-time generation circuitry is used to prevent shoot-through currents in the bridge. The dead-time can be adjusted by changing the value of the DT pin capacitor and resistor. A larger capacitor and resistor value will increase the dead-time, while a smaller value will decrease it.
