| Pin | Project name | Official function | Number/name match | Metadata issue |
|---|---|---|---|---|
| 1 | +VIN | Positive input voltage | Yes | Pin Type is Unspecified; no Pin Description |
| 2 | DEN | Detection and enable | Yes | Pin Type is Unspecified; no Pin Description |
| 3 | T2P | Type-2 PSE indicator | Yes | Pin Type is Unspecified; no Pin Description |
| 4 | VC | Controller voltage | Yes | Pin Type is Unspecified; no Pin Description |
| 5 | −VIN | Negative input voltage | Yes | Pin Type is Unspecified; no Pin Description |
| 6 | −VOUT | Negative output voltage | Yes | Pin Type is Unspecified; no Pin Description |
| 7 | +VOUT | Positive output voltage | Yes | Pin Type is Unspecified; no Pin Description |
Pin Type: Unspecified and lacks a human-readable Pin Description. This does not change physical connectivity but weakens ERC, search, and downstream documentation.Part Type: Integrated Circuits is not wrong at a high level, but “Isolated DC-DC Converter Module” or “Power Module” would be more precise.Result
