# HL90217

**Hallwee** · Hall Switches · TO-92S

HL90217 from Hallwee, in a TO-92S. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input, operating range 6.5 V to 24 V per the electrical characteristics table. |
| 2 | GND | power_in | Ground pin; the datasheet pin table lists it as a power pin. |
| 3 | Output | output | Open-drain output driver with short-circuit protection, max output current 25 mA and saturation voltage 600 mV max at VDD = 12 V, IOUT = 25 mA. |

## CAD (KiCad official)

- Symbol: `HL90217`
- Footprint: `Package_TO_SOT_THT:TO-92_Inline`
- 3D model: TO-92S (KiCad packages3D, STEP)
- 3D model files: `hl90217-etched.step` / `hl90217-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hl90217.step` / `hl90217.glb` are the bare package body.
