# 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. |

## CAD (KiCad official)

- 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.
