# KTH1701SL-TO3

**CONNTEK** · Linear Hall Sensors · TO-92S

KTH1701SL-TO3 from CONNTEK, in a TO-92S. 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; a 1 µF capacitor between VDD and ground placed as close to the pin as possible is recommended to filter supply noise. |
| 2 | GND | power_in | Ground reference pin for the chip supply. |
| 3 | OUTPUT | output | CMOS push-pull Hall switch output that goes low when the magnetic field exceeds BOP and returns high when it drops below BRP, with an absolute maximum output drive current of 5 mA. |
