DRV5055A1QDBZR

Texas Instruments · Hall Sensor · SOT-23

DRV5055A1QDBZR from Texas Instruments, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Power supply input, 3 V to 3.63 V or 4.5 V to 5.5 V. TI recommends connecting this pin to a ceramic decoupling capacitor of at least 0.01 µF to GND.
2 OUT output Analog output voltage. Quiescent voltage is VCC/2 (B = 0 mT); voltage swings proportionally with applied magnetic flux density (sensitivity from 12.5 mV/mT to 100 mV/mT depending on variant). Can drive ±1 mA.
3 GND power_in Ground reference for the device.

Two STEP files. Same geometry, different body top:

File Size Use it when
drv5055a1qdbzr.step 59 KB You want the bare part, or you mark your own boards.
drv5055a1qdbzr-etched.step 2.4 MB You want the part with DRV5055A1QDBZR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 583 faces against 69 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (33 pp, sha256 834226c4602ad561, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
