KTH1601TH-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 1.6V to 5.5V, with a recommended 1uF typical bypass capacitor placed close to the pin. |
| 2 | OUTPUT | output | Push-pull output pin (VOL 0.05V typ, VOH VDD-0.05V typ at IOUT=1mA) that turns on when flux exceeds BOP and off below BRP; absolute maximum output current is 5mA. |
| 3 | GND | power_in | Ground pin. |
