SC28L92A1A,518 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital sections separate, and use a common ground point for the analog and digital grounds.
• How do I ensure reliable communication between the SC28L92A1A and the microcontroller?
  Use a reliable communication protocol like SPI or I2C, and ensure proper signal termination and routing. Also, use a common clock source and ensure the microcontroller's clock frequency is within the SC28L92A1A's specified range.
• What are the thermal considerations for the SC28L92A1A?
  The SC28L92A1A has a maximum junction temperature of 150°C. Ensure good thermal conductivity between the device and the PCB, and consider using thermal vias or a heat sink for high-power applications.
• How do I handle ESD protection for the SC28L92A1A?
  Use ESD protection devices like TVS diodes or ESD arrays on the input/output lines, and ensure the PCB design includes ESD protection features like guard rings and ESD-safe layout practices.
• What are the power sequencing requirements for the SC28L92A1A?
  Power up the analog supply (VDDA) before the digital supply (VDDD), and ensure the power-up sequence is within the specified voltage and timing requirements.
