DRV8806PWPR Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the VM pin?
  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.
• How do I adjust the current limit on the DRV8806PWPR?
  The current limit 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.
• What is the purpose of the EN pin, and how do I use it?
  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 function or to reduce power consumption when the driver is not in use.
• How do I protect the DRV8806PWPR from over-temperature?
  The DRV8806PWPR has a built-in thermal shutdown feature that turns off the driver when the junction temperature exceeds 170°C. However, it's recommended to implement external thermal protection measures, such as a thermal sensor or a heat sink, to prevent overheating.
• What is the minimum input voltage required for the DRV8806PWPR to operate?
  The minimum input voltage required for the DRV8806PWPR to operate is 8V, but it's recommended to use a minimum of 10V for reliable operation.
