KTM1331SE-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 supply voltage is 1.8 V to 5.5 V, with an absolute maximum supply voltage of 6 V and a reverse voltage limit of -0.3 V. |
| 2 | OUTPUT | output | Push-pull latch output that turns on when the magnetic flux exceeds BOP and off when it falls below BRP; output current is limited to 5 mA absolute maximum. |
| 3 | GND | power_in | Ground pin. |
