KTH4603AB-ST3 from CONNTEK, in a SOT-23-3L. 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 2.5 V to 5.5 V (absolute max 6 V), with a 1 µF filter capacitor recommended close to the pin. |
| 2 | OUT | output | NMOS open-drain output that goes low when the field exceeds BOP (about 25 Gs) and is released when it falls below BRP; max drive current 30 mA. |
| 3 | GND | power_in | Ground reference for the supply and output. |
