KTM1301SE-ST3

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

KTM1301SE-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 range 1.8 V to 5.5 V (absolute maximum 6 V, reverse supply -0.3 V); a 100 nF capacitor should be placed between supply and ground as close to this pin as possible to filter supply noise.
2 OUTPUT output CMOS push-pull output that goes low when the field exceeds BOP and high when it falls below BRP, with output current limited to 5 mA absolute maximum (VOL max 0.05 V and VOH min VDD-0.05 V at IOUT = 1 mA).
3 GND power_in Ground reference pin for the device, to which the supply decoupling capacitor is connected.
