Eval

  • Pressing On-button must switch 240V line
  • Battery driven?
    • Will there be an plumbum battery or only regular powersupply
  • A simple 1,5V Alkali will do.
  • Button can handle 240V
  • An 18650 is perfect. Along with the MCP73871 or only MAX1811ESA+. No integrated LDO necessary, only SSR is switched. AUR9811DGD only 33 Cents.
  • Single-Button can be realised by bringing signal to mosfet along with diodes
  • Simple STM32F042 can be used
  • Mini-USB connector for direct charge.
  • 5V AC/DC Wandler integrieren; 5W, >80% efficienty
  • Strom messen; STM32-32K-Variante sinnvoll; sinnvoller wie Akku messen der eh bestromt wird wenn geraet eingeschalten ist.
    • Liegt altes Design noch wo rum?
