**CONNTEK** · Hall Switches · SOT-23-3L

KTH1702CC-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 | Supply input for the sensor, with an operating range of 1.8 V to 5.5 V and an absolute maximum VDD of 6 V. |
| 2 | OUTPUT | output | Open-drain output that goes low when the field exceeds the operating point BOP and returns high when the field falls below the release point BRP, with a maximum output drive current of 5 mA. |
| 3 | GND | power_in | Ground pin for the device. |
