KTM1301SC-ST3

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

KTM1301SC-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 for the sensor, which operates from 1.8 V to 5.5 V; a 100 nF capacitor should be placed as close as possible to this pin for noise filtering.
2 OUTPUT output CMOS push-pull output that goes low when the magnetic field exceeds BOP and high when it falls below BRP, with an absolute maximum output drive current of 5 mA.
3 GND power_in Ground reference pin, to be decoupled to VDD with a 100 nF capacitor connected between supply and ground.
