MT9101ET

Magn Tek · Hall Sensor · SOT-23

MT9101ET from Magn Tek, 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 Supply voltage input, 3.0 V to 5.5 V operating range (30 V absolute max). Typical supply current 6.7 mA @ Vcc=5V. Bypass with a local decoupling capacitor to GND.
2 Out output Ratiometric analog output. Quiescent voltage is Vcc/2 (2.500 V typ @ Vcc=5V; 1.650 V typ @ Vcc=3.3V) at B=0 and swings linearly with magnetic flux density. Output resistance ~2 Ω; source/sink capability ±1.5 mA; recommended external load ≥4.7 kΩ, load cap ≤10 nF.
3 GND power_in Ground / power return.

  • Symbol: MT9101ET
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mt9101et-etched.step / mt9101et-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mt9101et.step / mt9101et.glb are the bare package body.

Provenance

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

  • Datasheet: Magn Tek datasheet (12 pp, sha256 a002ba99c385ccb1, retrieved 2026-08-17, tier: lcsc)
  • 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).
