KTM1301SD-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, operating from 1.8 V to 5.5 V; a 100 nF capacitor should be placed between this pin and ground as close to the 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 it falls below the release point BRP; output drive current is limited to 5 mA absolute maximum. |
| 3 | GND | power_in | Ground reference for the supply and the output stage, with the 100 nF VDD decoupling capacitor returned to this pin. |
