Hardware Engineer Design-In & PCB Layout Checklist

  • Bypass Capacitors: Place a 100nF low-ESR ceramic capacitor directly adjacent to the power supply pins and return ground plane within 2mm trace distance.
  • Signal Routing: Keep high-speed or differential signal traces short, symmetrical, and avoid routing over split ground planes.
  • Thermal Management: For high-current or power packages, connect exposed thermal ground pads to multiple copper thermal vias into inner ground layers.
  • ESD Protection: While COS3201 incorporates on-chip ±4kV HBM ESD protection, optional external bidirectional TVS diodes can be added for harsh field cable terminals.
