KTH1701FH-ST3

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.
