SG6858TZ Frequently Asked Questions (FAQs)

  • 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 with a thermal resistance of 10°C/W or lower, and ensure good airflow around the device. Also, consider derating the output current at high temperatures.
  • The maximum allowed voltage on the enable pin (EN) is 6V. Exceeding this voltage may damage the device.
  • Yes, the SG6858TZ is AEC-Q100 qualified and suitable for high-reliability and automotive applications. However, ensure you follow the recommended operating conditions and design guidelines.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and add a common-mode choke or EMI filter to reduce emissions.
