EN5311QI Frequently Asked Questions (FAQ)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from the power plane to minimize noise and EMI.

  • Use a heat sink with a thermal interface material to keep the junction temperature below 125°C. Ensure good airflow and avoid blocking the airflow around the device.

  • The maximum allowed power dissipation is 1.5W. Ensure that the device is operated within the recommended operating conditions to avoid overheating.

  • Use a logic analyzer or oscilloscope to monitor the signals. Check the power supply voltage, clock signal, and data signals for any anomalies. Consult the datasheet and application notes for troubleshooting guidelines.

  • No, the EN5311QI is not designed for radiation-hardened applications. It is intended for commercial use only. For radiation-hardened applications, consider using a different device specifically designed for that purpose.
