KTM1331TC-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; the datasheet specifies an operating supply range of 1.8 V to 5.5 V. |
| 2 | OUTPUT | output | Push-pull output that turns on when the magnetic flux density exceeds BOP and turns off when it falls below BRP (17 Gauss operate point for the KTM1331TC variant). |
| 3 | GND | power_in | Ground pin. |
