Progetto FCU/Driver Board HPA
Thought
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).
Thought for 7 mins 34 sec
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:
- Completa la rete esterna del buck U1 (L, CIN/COUT, BST, VCC/LDO cap) secondo datasheet
- Corregge U1 EN/ENCLK (ora su VBAT, ma il datasheet dice max +4.5 V su “all other pins”)
- Sistema il trigger: oggi U3 e’ bypassato perche’ ingresso/uscita finiscono sulla stessa net; separo TRIG_RAW -> TRIG_FILT -> TRIG_BUF verso U2
- Aggiunge pull-up + testpoint su PG e lascia D4/R8 DNP documentati
- ERC finale
