Thermal Protection:

Embedded thermal shutdown to prevent overheating during high-current charging cycles. 8681l ic datasheet

  • Thermal: spread heat with copper pours, add thermal vias, or move high-dissipation components.
  • EMI: add input/output LC filters, place decoupling capacitors close to pins, route switching nodes away from sensitive analog traces.
  • Stability: use capacitors with correct ESR, follow recommended layouts, and, if needed, add small series resistances or snubbers.
  • Sequencing: add supervisor ICs or design passive RC delays to ensure proper rail startup order.
