Add TIDA-00699 power supply reference schematic

[AnasSarkiz]

Summary

• add the TIDA-00699 off-battery power-supply reference as PowerSupply_TIDA00699
• reproduce the 79-part schematic netlist, source component placement, values, ratings, footprints, test points, control header, and DNP gate resistors
• add reusable TI definitions for LM74610-Q1, LM25122-Q1, LM53603-Q1, TPS3808-Q1, and CSD18531Q5A
• use explicit JSX traces and fixed source coordinates, following the reviewed patterns in Add TIDA-020027 TLIN1028 communication interface #129 and Add BQ40Z60 battery pack subcircuit #135
• omit passive manufacturer part numbers, following the repository convention established in Add TIDA-020027 TLIN1028 communication interface #129
• update to the latest published tscircuit version, 0.0.2422
• keep the contribution schematic-only: no PCB placement, routing, or PCB snapshot is included

Reference selection

The obstacle-detection power-supply block lists three candidate designs. Ranked from easiest/smallest to largest:

1. TIDA-00699 (selected) — one functional schematic page plus notice; a focused off-battery front end with protection, 9-V boost, 5-V buck, and supervisor.
2. TIDA-01492 — six schematic pages and a multi-rail supply architecture.
3. TIDA-01425 — thirteen schematic pages covering a complete gateway platform with processor, memory, communications, and multiple power domains.

TIDA-00699 is both the smallest candidate and the closest functional match for subsystem 21583.

Reference vs generated schematic

• TI reference schematic PDF
• Generated schematic snapshot

Known renderer limitation

The reference netlist and source placements are preserved. The active schematic router still renders one short U2 VCC branch as a fallback U2_VCC net label instead of the reference wire geometry. The fallback is intentionally left visible rather than hidden with decorative lines or invented connectivity.

Validation

• bun run format:check
• bunx tsc --noEmit
• bunx tsci version → 0.0.2422
• bunx tsci check netlist lib/subcircuits/PowerSupply_TIDA00699.circuit.tsx → 0 errors, 0 warnings
• schematic-only snapshot generated and visually compared with the source
• bunx tsci build lib/subcircuits/PowerSupply_TIDA00699.circuit.tsx --disable-pcb --schematic-only --svgs --disable-parts-engine

Superseded by #149. The replacement preserves the same TIDA-00699 implementation on a clean branch based on the current main, includes the PR #129/#135 review conventions, and validates with tscircuit 0.0.2448.
