Part Review and Datasheet Update
Thought for 3 mins 10 sec
Done — I found the official NVE datasheet and added the missing
Summary
Datasheet URL project property as https://www.nve.com/Downloads/ALTxxx-10.pdf. For part-project reviews like this, the correct flow is to confirm whether Datasheet URL exists, set it if missing, then compare symbol/footprint/pin metadata against the datasheet pin table and package infoTable
| Category | Result |
|---|---|
| Datasheet URL | Updated to official NVE PDF |
| Existing project properties before review | Manufacturer Part Number = ALT025-10E-TR7, Designator Prefix = U |
| Datasheet manufacturer | NVE Corporation |
| Datasheet family | ALT-Series TMR Analog Magnetometer Sensors |
| Datasheet package | 2.5 mm x 2.5 mm DFN6 with exposed center pad |
| Symbol terminal count | 7 total |
| Footprint/pad count | 7 pads total |
| Pin descriptions | Missing on all terminals |
| Pin types | Present but all set to Unspecified |
| Pin numbering vs datasheet | Matches |
| Footprint package intent vs datasheet | Matches |
Table
| Spec | Value |
|---|---|
| Part | ALT025-10E |
| Function | Analog TMR magnetometer / bridge magnetic sensor |
| Sensing range | ±10 mT |
| Saturation field | 30 mT |
| Sensitivity | 6 min / 8 typ / 10 max mV/V/mT |
| Supply voltage | 0 to 10 V operating |
| Absolute max supply | 14 V |
| Bridge resistance | 8 min / 20 typ / 55 max kOhm |
| Bandwidth | DC to 350 kHz |
| Hysteresis | 1 %FS |
| Operating temperature | -40 to 125 C |
The current symbol matches the datasheet pin mapping:
Footprint cross-check
The footprint assets indicate a DFN6 2.5 x 2.5 mm, 0.65 mm pitch package with exposed pad, which aligns with the datasheet package. The footprint has pads for
Mismatches / issues found
OUT+, NC, GND, OUT-, NC, VCC, and EPAD, so the pad count and naming structure are consistent with the datasheet package and pinout.Table
| Item | Status | Notes |
|---|---|---|
| Datasheet URL | Fixed | Missing before; now added |
| Manufacturer Name property | Missing | Datasheet says NVE Corporation |
| Package or Case Code property | Missing | Should reflect DFN6 2.5 x 2.5 mm package |
| Part Type property | Missing | This is a magnetic sensor / magnetometer sensor |
| Pin Type | Incomplete | All terminals are Unspecified |
| Pin Description | Missing | None of the terminals have descriptions |
| Section / Pin Group | Missing | Not populated |
There is no pin-count mismatch. The only representational difference is that the datasheet describes a center pad, while the project models it as EPAD with Pin Number 7. That is a normal CAD convention and not a functional mismatch. The sync workflow explicitly treats exposed pads as pins that must be represented in the part model
Bottom line
- The symbol and footprint are structurally correct for ALT025-10E-TR7.
- The main gaps are metadata quality, not pin mapping:
- missing
Manufacturer Name - missing
Part Type - missing
Package or Case Code - missing pin descriptions
- all pin types left as
Unspecified
- missing
If you want, I can do the next cleanup pass and populate the missing project properties plus terminal
Pin Type and Pin Description fields from the datasheet.Fill missing metadata
Set manufacturer fields
Check exposed pad
Set Datasheet URL to "https://www.nve.com/Downloads..."
