KTM1301TC-ST3

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

KTM1301TC-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 from 1.8 V to 5.5 V, with an absolute maximum of 6 V; a 100 nF capacitor should be placed as close to this pin as possible to filter supply noise.
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 output drive current rated at 5 mA maximum.
3 GND power_in Ground pin for the device.
