A datasheet evidence checklist for AI-assisted circuit design

Ask for the document and page first

A value without evidence can't be checked. Ask for the document and the printed page number from the start.

Find [value name] for [part number] in its datasheet.
- Give the document (manufacturer, revision, date) and the printed page number.
- Give the test conditions (temperature, voltage, current) next to the value.
- Mark whether it is typical or a min/max limit, and whether it was read from a table or a graph.
- If you can't find a value, don't estimate it. Say it was not found.

What to check in the answer

1. Document and page: does the answer give the document and page number? A value without a page may have come from memory.
2. Manufacturer and part number: do the manufacturer and part number printed on that page match what you asked? Check the ordering code suffix too (package, temperature grade, packing).
3. Test conditions: do the temperature, voltage and current next to the value match your design? A 25 °C value is not a full-temperature-range value.
4. Typical vs. min/max: was a typical value used as if it were guaranteed? Set design margin from the min/max limits.
5. Values read from graphs: if the value is not in a table, which figure and which curve was it read from? A graph value is an estimate between grid lines.
6. Revision: which revision and date is the document? If it is old, check the latest revision on the manufacturer's site.
7. Package-dependent values: is the thermal resistance or pinout the one for the package you actually use?
8. Passives: were resistors, capacitors and inductors checked too, for rated voltage and temperature characteristics? They are easy to skip in a BOM.
9. Unconfirmed values: does the answer mark the values it could not find? If not, ask again.

PartsPlan finds the evidence in the original datasheet. You and your AI judge the circuit from that evidence.

If it says there is no document

"No document" can mean it has not been collected yet or the part number was written differently. It does not mean the part has no datasheet. Check the spelling and the ordering code of the part number first.

• Ask your AI to request it, or leave the part number on the datasheet request page. Once it has been collected, your AI can find it.
• If you can't wait, check the original on the manufacturer's site. That information is not PartsPlan evidence, so note its source separately.
• If the AI filled in a value without a document, don't use it until you have checked it against the original.

What page evidence changes

With a page number, you can check each item above against the original right away. Without one, you have to find the value again from scratch.

We gave the same AI the same 8 design questions. Correct value and printed page: with PartsPlan MCP 8 / 8, web search only 6 / 8 (September 25–27, 2026; a small test, and we chose the 8 documents. A web search re-run on September 27 got 7 / 8 in 8.4 min, relying on third-party copies).
