CONNTEK · Hall Switches · SOT-23-3L
KTH1701FH-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; the operating supply range is 1.8 V to 5.5 V, and a 1 µF capacitor should be connected between VDD and ground as close to the VDD pin as possible to filter supply noise. |
| 2 | OUTPUT | output | CMOS push-pull switch output; the absolute maximum output drive current is 5 mA, and at IOUT = 1 mA the output low level is 0.15 V max and the output high level is VDD − 0.15 V min. |
| 3 | GND | power_in | Ground reference pin for the device. |
