Work done
  • Reemplacé J1 por KF128-5.08-2P-AA y mantuve el mismo designador.
  • Restauré la conectividad de entrada de batería exactamente en los mismos nodos: J1 pin 1 a VBAT_RAW y pin 2 a GND.
  • Verifiqué que la cadena funcional aguas abajo permanece intacta: Q3 sigue tomando VBAT_RAW, luego el filtro con L1, y el bloque de control con U2, Q2 y Q1 no fue alterado.
  • Actualicé la documentación en Project Specification y Design Notes.
Success criteria review
  • ✅ El nuevo conector J1 quedó integrado como KF128-5.08-2P-AA.
  • ✅ Se preservaron todos los nets de entrada de batería y su polaridad original.
  • ✅ La funcionalidad del sistema de corte se mantiene intacta: la red de histéresis y la cadena de protección/conmutación no fueron modificadas, conservando el objetivo de 12.0 V de desconexión y 12.8 V de reconexión.
  • ✅ La documentación del proyecto refleja el cambio de conector y el mapeo de conectividad.
Next steps Si quieres, puedo seguir con una revisión de layout para confirmar huella, orientación mecánica y espacio alrededor del nuevo bornero J1.
