# KTH1701TU-ST3

**CONNTEK** · Linear Hall Sensors · SOT-23-3L

KTH1701TU-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 from 1.8 V to 5.5 V, with a 1 µF capacitor recommended between VDD and ground placed as close to the pin as possible to filter noise. |
| 2 | OUTPUT | output | CMOS push-pull output that goes low when the magnetic induction exceeds BOP and returns high when it drops below BRP, with output drive current rated at 5 mA maximum. |
| 3 | GND | power_in | Ground reference for the supply and output of the device. |
