CONNTEK · Hall Switches · SOT-23-3L
KTH1631FU-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 range is 1.6 V to 5.5 V per the recommended operating range, with an absolute maximum supply voltage of 6 V. |
| 2 | OUTPUT | output | Magnetic switch output that turns on (Low) when the magnetic flux density exceeds BOP and turns off (High) when it falls below BRP, with an absolute maximum output current of 5 mA. |
| 3 | GND | power_in | Ground pin. |
