Scope status
- Datasheet URL: completed with platform normalization. The official TI URL was written:
https://www.ti.com/lit/ds/symlink/tmag5231.pdf - Flux subsequently ingested the PDF and stores the effective property as:
https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/3408ca2a184c374efc0e0f78891d04fb55e6d5ea39663a2fc5d6c0ccc9a6e01a.pdf - Verification: live
selfdatasheet queries now succeed and identify TMAG5231 Rev D, SLYS042D. - No intentional metadata or geometry edits were made beyond setting the Datasheet URL. The URL conversion is automatic platform behavior.

TMAG5231C1DQDBZR - Symbol Style:
parametric-v1 - Datasheet URL: Flux-hosted ingested copy shown above, sourced from the requested official TI URL
- Pinout: matches TI exactly: 1 VCC, 2 OUT, 3 GND.
- Pad size: footprint is 1.24 × 0.59 mm, versus TI recommendation 1.30 × 0.60 mm. Undersized by 0.06 × 0.01 mm.
- Pitch/spacing: pad centers use ±0.95 mm on the two-pin side, giving 1.90 mm center separation. Opposing-side center span is 2.11 mm, essentially TI’s 2.10 mm dimension (+0.01 mm).
- Package dimensions: TI confirms 1.12 mm maximum height and body 2.80–3.04 × 1.20–1.40 mm. The fab outline is 2.92 × 1.30 mm, matching the nominal midpoint.
- Pin descriptions: absent in the part. TI descriptions are:
- VCC: 1.65–5.5 V supply; TI recommends at least 0.1 µF ceramic to ground
- OUT: omnipolar output responding to north and south poles
- GND: ground reference
- Electrical types: OUT is correct. VCC and GND are both represented as
Power In; GND would conventionally be typed Ground. - Per instruction, these mismatches were reported only and not corrected.

Audit complete. I added the official TI datasheet URL and verified the 3-pin mapping; key mismatches are the
SOT-23-5 package metadata, incorrect release-point text, missing pin descriptions, and slightly undersized footprint pads.Full results: TMAG5231C1DQDBZR Part Datasheet Audit.

Result
The part was checked against the official Texas Instruments TMAG5231 Low-Power, Hall Effect Switch, Rev. D (SLYS042D) datasheet. The live project initially had no usable
datasheet_url; the official URL was set to:Flux ingested the PDF and may display an internally hosted copy as the effective property. Live datasheet queries now work.

Symbol and pin audit
Table
| Pin | Symbol name | Symbol type | Datasheet function | Result |
|---|---|---|---|---|
| 1 | VCC | Power In | 1.65–5.5 V supply; connect at least 0.1 µF ceramic to GND | Number/name correct; description missing |
| 2 | OUT | Output | Omnipolar output responding to north and south poles | Correct; description missing |
| 3 | GND | Power In | Ground reference | Number/name correct; description missing; Ground type would be clearer |
The schematic symbol contains exactly three terminals and the pin mapping matches the DBZ top-view pinout.
Footprint audit
Footprint source:
SOT95P237X112-3N.kicad_modTable
| Feature | Effective footprint | TI recommended land pattern | Result |
|---|---|---|---|
| Pad count | 3 | 3 | Correct |
| Pad size | 1.24 × 0.59 mm | 1.30 × 0.60 mm | Slightly undersized by 0.06 × 0.01 mm |
| Two-pin-side pitch | 0.95 mm | 0.95 mm | Correct |
| Two-pin center separation | 1.90 mm | 1.90 mm | Correct |
| Opposing-side center span | 2.11 mm | 2.10 mm | +0.01 mm, negligible |
| Fab body | 2.92 × 1.30 mm | Nominal 2.92 × 1.30 mm | Correct |
| Solder paste | Present, nominally 1:1 | Stencil example matches pad geometry | Acceptable |
| Solder mask | +0.102 mm expansion | TI example shows 0.07 mm clearance | Larger than TI example; verify against fab capability |
Pad mapping is correct: pad 1 VCC, pad 2 OUT, pad 3 GND. The footprint is broadly compatible with DBZ0003A but does not exactly reproduce TI’s recommended pad and mask dimensions.
Description/property mismatches
- Package case code is
SOT-23-5, but this device is a 3-pin SOT-23, TI DBZ package. - The description says “±0.8 mT typical release point.” This is incorrect: ±0.8 mT is the typical hysteresis; the typical release point is ±2.2 mT at 25°C.
- Pin descriptions are absent for all three terminals.
- GND is electrically typed
Power Inrather thanGround. - Footprint pads are slightly smaller than TI’s example land pattern, and mask expansion is larger.
Overall assessment
The pinout, pin count, nominal package body, pitch, and functional identity are correct. The part is usable with caution, but the package metadata and description should be corrected, and the footprint dimensions should be reviewed against the intended assembly process before production.
