DRV8873SPWPR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 45V. However, it's recommended to keep it below 40V for reliable operation.
  • The sense resistor value depends on the desired current limit and the sense amplifier gain. A good starting point is to use the formula Rsense = 0.5V / Itrip, where Itrip is the desired current limit. Then, adjust the value based on the specific application requirements.
  • 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 DRV8873 from back-EMF, use a flyback diode (D1) in parallel with the inductive load. This diode absorbs the back-EMF voltage and prevents it from damaging the driver.
  • The DRV8873 can handle switching frequencies up to 100 kHz. However, the actual frequency limit depends on the specific application, load, and PCB layout.
