Part Review and Datasheet Verification
Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.
Thought for 6 sec
I’ll review the part metadata, find and attach the official datasheet if needed, then compare the symbol, footprint, and pin descriptions against the datasheet and report any mismatches.

I found the official NVE ALT-series datasheet and recorded its URL in the project metadata; now I’m checking the pinout and DFN footprint details against it.

Reviewed ALT024-10E against the official NVE datasheet and created the detailed report in project docs: ALT024-10E Part Review (
alt024-10e-part-review).Key findings: pins 1–6 match the datasheet, the 7-pad DFN6 structure is consistent, and the official datasheet is
https://www.nve.com/Downloads/ALTxxx-10.pdf. Main mismatches are that Part Type is set to “Transistors” instead of sensor/magnetometer, and pad 7 is labeled/type-treated as GND-PAD / Power In even though the datasheet describes it as an exposed leadframe pad, not GND.Fix metadata and recheck

Datasheet pinout
Table
| Pin / pad | Datasheet name | Datasheet function | Project symbol/footprint label | Result |
|---|---|---|---|---|
| 1 | Out+ | Positive bridge output | OUT+ | Match |
| 2 | NC | No internal connection | NC | Match |
| 3 | GND | Negative bridge supply / ground | GND | Match |
| 4 | Out− | Negative bridge output | OUT- | Match |
| 5 | NC | No internal connection | NC | Match |
| 6 | VCC | Positive bridge supply | VCC | Match |
| 7 / center exposed pad | Exposed pad / leadframe | Internally connected to leadframe, not specified as GND or VCC | GND-PAD | Mismatch / should be renamed or described as exposed pad / leadframe |
Footprint cross-check
Datasheet package dimensions:
- Body: 2.50 ± 0.10 mm × 2.50 ± 0.10 mm
- Height: 0.80 +0/−0.10 mm
- Terminal pitch: 0.65 mm typical
- Six lead terminal size: 0.30 ± 0.05 mm
- Exposed pad: 2.00 ± 0.05 mm × 1.30 ± 0.05 mm
- Pin-1 chamfer / ID: C0.10
Official NVE KiCad footprint resource pad geometry:
- Pads 1–6: 0.35 × 0.60 mm at x = −0.65, 0, +0.65 mm and y = ±1.25 mm
- Pad 7: 2.00 × 1.30 mm centered at 0,0
Current Flux footprint observations:
- Pad count is correct: six perimeter pads plus one center pad.
- Pad labels align with the datasheet pinout for pins 1–6.
- Silkscreen/fab outline visually shows a 2.5 mm square body and pin-1 indicator.
- Tool output did not expose exact current pad sizes/coordinates, so exact land-pattern dimension matching could not be fully proven from structured inspection. Available visual geometry appears consistent with the 2.5 × 2.5 mm DFN6 outline.
Mismatches and recommendations
- Part Type is set to “Transistors,” but the datasheet describes this as a TMR analog magnetic sensor / magnetometer. Recommended: change Part Type to Sensor if available.
- Pad 7 is labeled “GND-PAD,” but the datasheet says the center pad is internally connected to the leadframe and is not identified as ground. Recommended: rename/describe pad 7 as EP, PAD, or LEADFRAME; avoid implying it must be tied to GND unless NVE’s application guidance explicitly says so.
- Datasheet URL was missing from visible project properties. Official URL found: https://www.nve.com/Downloads/ALTxxx-10.pdf. I recorded it in Implementation Details because the available project-property editor did not expose a dedicated Datasheet URL field.
- Pin 7 Pin Type is currently Power In via the GND-PAD terminal. Recommended: change to Passive/Mechanical/Exposed Pad if the platform supports it.
Overall verdict
The pinout for pins 1–6 and the 7-pad DFN6 structure are consistent with the NVE datasheet. The main issues are metadata classification and the exposed pad naming/type: pad 7 should not be treated as a normal GND supply pin based on the datasheet wording.
