KTH1702AE-ST3
CONNTEK · Hall Switches · SOT-23-3L
KTH1702AE-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, operating over 1.8 V to 5.5 V with an absolute maximum of 6 V; a 1 µF capacitor between VDD and GND is recommended close to the pin to filter supply noise. |
| 2 | OUTPUT | output | Open-drain output that goes low when the magnetic field exceeds the operate point BOP and stays low until the field drops below the release point BRP, when it goes high; an external pull-up is needed. |
| 3 | GND | power_in | Ground pin. |
