VNQ860SP-E datasheet by STMicroelectronics

VNQ860SP-E Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics recommends a 2-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.
• How do I ensure reliable operation in high-temperature environments?
  Use a heat sink, ensure good airflow, and consider derating the device's power handling at high temperatures (above 125°C).
• What is the maximum allowed voltage on the input pins?
  The maximum allowed voltage on the input pins is 35V, but it's recommended to keep it below 30V for reliable operation.
• Can I use the VNQ860SP-E in a high-reliability application?
  Yes, the VNQ860SP-E is qualified for automotive and industrial applications, and it's suitable for high-reliability applications with proper design and testing.
• How do I troubleshoot issues with the device's output voltage regulation?
  Check the input voltage, output load, and PCB layout for any issues. Use an oscilloscope to measure the output voltage and check for any oscillations or noise.
