VNQ860-E datasheet by STMicroelectronics

VNQ860-E Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics provides a recommended PCB layout in the application note AN4898, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
• How do I select the correct external components for the VNQ860-E?
  STMicroelectronics provides a component selection guide in the datasheet, which includes recommendations for capacitors, resistors, and inductors. Additionally, the application note AN4898 provides more detailed guidance on component selection.
• What is the maximum allowed voltage on the VIN pin?
  The maximum allowed voltage on the VIN pin is 36V, as specified in the datasheet. Exceeding this voltage may damage the device.
• How do I implement overcurrent protection with the VNQ860-E?
  The VNQ860-E has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) between the VIN pin and the GND pin, and set the overcurrent threshold (Ilim) using an external resistor (Rlim) connected between the Ilim pin and the GND pin.
• 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 VNQ860-E. When the EN pin is high, the device is enabled, and when it's low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device when not in use.
