Progetto FCU/Driver Board HPA

flux

Work done
  • Confirmed 2S-only intent on the existing schematic (rails: ^VBAT 6.0-8.4 V, ^VBAT_SOL; logic rail ^+3V3) and kept functional values/roles intact (gate network, divider, decoupling, etc.)
  • Assigned manufacturer-backed MPN properties to all generic passives while keeping values unchanged: R2, R3, R4, R5, R6, R7, R1, C1, C2, C3, C4, C5, C6
  • Confirmed optional shunt R8 remains DNP (Exclude from BOM = 1) and documented its population guidance
  • Added the optional solenoid fast-clamp TVS footprint D4 across ^VBAT_SOL to ^SOL_NODE and set it DNP by default
Success criteria review
  • ✅ All generic passive components now have manufacturer/MPN properties suitable for ordering from general distributors
  • ✅ Optional solenoid fast-clamp footprint added as D4 and marked DNP
  • ✅ BOM properties normalized with manufacturer/MPN/package updates and DNP flags where applicable
Next steps
  • If you want, I can swap the 3.3 V buck U1 to a part with better general-distributor availability (current BOM flags it as restricted at Mouser).

nope, its okay. gli schemi sono troppo generalizzati e poco specifici mi puoi fare uno schema preciso

flux

Vuoi uno schematico preciso (non “generalizzato”): posso sistemare quello attuale rendendolo datasheet-correct e pronto per layout/produzione.
Il piano ready_to_execute fa queste correzioni chiave:
  1. Completa la rete esterna del buck U1 (L, CIN/COUT, BST, VCC/LDO cap) secondo datasheet
  2. Corregge U1 EN/ENCLK (ora su VBAT, ma il datasheet dice max +4.5 V su “all other pins”)
  3. Sistema il trigger: oggi U3 e’ bypassato perche’ ingresso/uscita finiscono sulla stessa net; separo TRIG_RAW -> TRIG_FILT -> TRIG_BUF verso U2
  4. Aggiunge pull-up + testpoint su PG e lascia D4/R8 DNP documentati
  5. ERC finale
Se clicchi Start sulla barra del piano, applico le modifiche direttamente nel progetto.
