621SCMGI8 Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1mm clearance around the package for airflow and heat dissipation.
  • Power up the VCC and AVCC pins simultaneously, followed by the VREF pin. Ensure a power-on reset (POR) circuit to prevent incorrect operation during power-up.
  • Use a 0.1uF ceramic capacitor between VCC and GND, and a 10uF electrolytic capacitor between AVCC and GND. Place the capacitors as close to the pins as possible.
  • Use a dedicated reset IC or a discrete circuit with a capacitor and resistor to ensure a clean reset signal. Ensure the reset signal is asserted for at least 10ms to guarantee a proper reset.
  • Use a multi-layer PCB with a solid ground plane, and consider adding EMI filters and TVS diodes for ESD protection. Ensure proper shielding and grounding of cables and connectors.
