PCA8886TS/Q900/1,1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  NXP recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to dissipate heat efficiently. A minimum of 1 oz copper thickness is recommended.
• How do I ensure reliable operation in high-temperature environments?
  NXP recommends using a heat sink with a thermal resistance of ≤ 10°C/W and ensuring good airflow around the device. Additionally, derating the output current and voltage can help reduce thermal stress.
• What are the recommended input and output capacitors for this device?
  NXP recommends using X7R or X5R ceramic capacitors with a voltage rating of 10V or higher for input and output capacitors. The recommended capacitance values are 10uF for input and 22uF for output.
• How do I troubleshoot issues with the device's overcurrent protection?
  Check the input voltage, output current, and PCB layout for any signs of overheating or electrical stress. Verify that the device is properly configured and that the output current is within the recommended range.
• Can I use this device in a high-reliability or automotive application?
  Yes, the PCA8886TS/Q900/1,1 is AEC-Q100 qualified and suitable for high-reliability and automotive applications. However, additional testing and validation may be required to meet specific industry standards.
