A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane to improve heat dissipation.
Use a heat sink, ensure good airflow, and consider using a thermal interface material (TIM) to improve heat transfer. Also, follow the recommended operating conditions and derating guidelines.
The maximum allowed voltage on the VIN pin is 28V, but it's recommended to keep it below 24V for reliable operation and to prevent damage to the internal voltage regulator.
Yes, the QSE773 is AEC-Q100 qualified and suitable for high-reliability and automotive applications. However, ensure you follow the recommended operating conditions and guidelines for these applications.
Use a logic analyzer or oscilloscope to monitor the input and output signals. Check the power supply, input voltage, and output current. Consult the datasheet and application notes for troubleshooting guidelines.
