DRV8601ZQVR 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 18V. Exceeding this voltage may damage the device.
• How do I ensure the device is in a low-power state during shutdown?
  To ensure the device is in a low-power state during shutdown, make sure the EN pin is pulled low and the VM pin is at 0V. This will minimize power consumption.
• What is the recommended value for the bootstrap capacitor (CBOOT) and why is it necessary?
  The recommended value for the bootstrap capacitor (CBOOT) is 10nF to 100nF. It is necessary to provide a high-frequency decoupling path for the high-side FET gate driver and to reduce electromagnetic interference (EMI).
• How do I adjust the switching frequency of the device?
  The switching frequency of the device can be adjusted by changing the value of the RT resistor connected to the RT pin. A lower value of RT will result in a higher switching frequency, and vice versa.
• What is the purpose of the VCC pin, and how should it be connected?
  The VCC pin is used to power the internal logic and gate drivers of the device. It should be connected to a stable 5V power supply, and a 10uF to 22uF decoupling capacitor should be placed close to the VCC pin to filter out noise.
