KTM1331TC-ST3

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

KTM1331TC-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 specifies an operating supply range of 1.8 V to 5.5 V.
2 OUTPUT output Push-pull output that turns on when the magnetic flux density exceeds BOP and turns off when it falls below BRP (17 Gauss operate point for the KTM1331TC variant).
3 GND power_in Ground pin.
