KTM1301TA-ST3

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

KTM1301TA-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 chip operates from 1.8 V to 5.5 V, and a 100 nF capacitor should be placed between VDD and ground as close to the VDD pin as possible to filter supply noise.
2 OUTPUT output CMOS push-pull output that goes low when the magnetic field exceeds the operating point BOP and goes high when the field falls below the release point BRP, with an output drive current of 5 mA maximum.
3 GND power_in Ground pin; the datasheet's application note connects the 100 nF VDD decoupling capacitor between the supply and this ground.
