BQ25185 Charger Topology
Thought
La auditoría confirma que U1 tiene el mismo pinout y paquete DQA-10 que el nuevo objetivo, pero es un dispositivo ESD diferente y no puede calificarse como sustituto funcional. Crearé ahora la matriz completa, manteniendo criterios conservadores para todos los pasivos genéricos.

La matriz completa quedó creada con los 69 designadores y criterios conservadores de fabricación; cierro la auditoría sin cambios de diseño.
Thought
Auditoría completada para los 69 designadores, sin modificar esquema, PCB, nets, BOM, librerías, placement ni routing.
La matriz destaca como bloqueos principales: J1, cambio requerido de U1 a TPD4E05U06DQAR, U10, K1–K3, L1 y todos los pasivos genéricos sin MPN exacto. El proyecto permanece BENCH_ONLY.

Component Qualification Manifest — Brand NewDay Shadow PCB
Status: BENCH_ONLY / NOT FOR FABRICATION / NOT FOR ENERGIZATION
Scope: Component library-gap qualification manifest only. No schematic, PCB, nets, placement, routing, RF/antenna geometry, Gerbers, fabrication output, or machine/load connections were modified.
Scope: Component library-gap qualification manifest only. No schematic, PCB, nets, placement, routing, RF/antenna geometry, Gerbers, fabrication output, or machine/load connections were modified.
Qualification Rules
- Use the exact MPNs from the Brand NewDay briefs.
- Use only official manufacturer datasheet/package evidence for equivalence decisions.
- If pin/function/package equivalence is not verified from official datasheets, status is NO SUBSTITUTE / LIBRARY GAP.
- Existing schematic proxy parts are documentation placeholders only unless marked pin-compatible by official evidence.

Notes by Official Evidence Source
- TI CC1354P10 datasheet/package addendum: confirms CC1354P106T0RGZR, RGZ VQFN-48, 7 mm × 7 mm, 0.5 mm pitch, active production.
- Microchip MCP41HVX1 datasheet: confirms MCP41HV51-503E/ST is SPI, 50 kΩ, TSSOP-14; not MCP45HV I²C compatible.
- TI TPS63030 datasheet/package addendum: confirms TPS63030DSKR DSK SON/VSON-10 and pin table; R suffix is large tape-and-reel.
- TI LM5069 datasheet/package addendum: confirms LM5069-1 latch-off behavior and MM/MMX reel-quantity distinction in same VSSOP-10 DGS package.
- Omron G5LE official datasheet/product page: confirms G5LE-14 DC5 coil family/specs; exact Flux library part still absent.
- TI CSD13380F3 datasheet/package addendum: confirms CSD13380F3 and CSD13380F3T share same device/package; suffix is reel quantity.
- Coilcraft MSS1246T official datasheet/product page: confirms 68 µH MSS1246T-683 family electrical data; exact MSS1246T-683MLB library footprint still required.
Required Before Any PCB/Layout/DFM Phase
- Replace all NO SUBSTITUTE / LIBRARY GAP proxies with exact components or explicitly approve each residual proxy with official pin/footprint evidence.
- Re-run pin-by-pin schematic verification after replacement.
- Preserve BENCH_ONLY status until battery, LM5069 thresholds, RF/antenna, relay load interface, stackup/clearance, thermal, and DFM decisions are closed.
Preserved Constraints
- AIRTAG_CHG_SYS = U3.SYS + C5.1.
- U3.CE remains tied to AIRTAG_PACK_NEG/GND, never SYS.
- Q2/Q3 remain DNP / BENCH_ONLY.
- K1/K2/K3 contact pins 1/2/3 remain external/no-connect.
