Pixel 7 Car Power Mod
Thought for 10 sec
4 days
I’ll retry the complete datasheet and circuit audit now, covering every active device, the full power path, fault cases, thermal limits, and the 46 × 80 × 5 mm envelope. I’ll save the detailed pass/fail report in the project files and make no circuit changes unless a separate correction step is warranted.

Full Datasheet and Circuit Validation
Project: Pixel 7 USB-C Battery Emulator Validation type: Read-only schematic/BOM/connectivity/datasheet review
4 days
Full datasheet and circuit validation completed. Current verdict: FAIL—do not connect this revision to the phone yet. The main blockers are the undersized LM5176 current shunt, inadequately driven Q8, unverified charge-back protection, provisional compensation/capacitors, and oversized PCB.
Detailed calculations, component-by-component results, citations, and corrections are in Full Datasheet and Circuit Validation.
Suggested next steps
- Correct the safety/blocker findings.
- Revalidate the revised power stage and fault protection.
- Then redesign the PCB for the 46 × 80 × 5 mm envelope.
