BQ25185 Charger Topology

flux

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.

flux

Auditoría completada para los 69 designadores, sin modificar esquema, PCB, nets, BOM, librerías, placement ni routing.
Component and Footprint Qualification Matrix
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.

Matrix — Capacitors (Every Designator)
All capacitor symbols are electrically safe two-pin proxies. Because no exact capacitor MPN is specified, each footprint remains a GENERIC_PLACEHOLDER and blocks fabrication qualification. Pad count is two; package size is configured, but dielectric, tolerance, DC-bias derating, ESR and manufacturer land-pattern evidence are incomplete.

Matrix — Resistors (Every Designator)
All resistor symbols are electrically safe two-pin proxies. No exact resistor MPN is specified, so each configured package is a GENERIC_PLACEHOLDER. Two-pad count and nominal package sizes are present, but manufacturer land pattern, voltage coefficient, pulse rating and exact tolerance/power qualification are incomplete.
