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

KTM1301SB-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 datasheet gives an operating supply range of 1.8 V to 5.5 V and an absolute maximum of 6 V, and recommends a 100 nF capacitor between VDD and GND placed as close to the VDD pin as possible.
2 OUTPUT output Switch output, CMOS push-pull; it goes low when the field exceeds BOP and high when the field falls below BRP, with an absolute maximum output drive current of 5 mA.
3 GND power_in Ground reference for the supply and output.
