KTM1301TB-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 with 6 V absolute maximum; a 100 nF capacitor placed close to the VDD pin is recommended to filter supply noise. |
| 2 | OUTPUT | output | CMOS push-pull switch output that goes low when the parallel magnetic field exceeds BOP and high when it falls below BRP, with 5 mA absolute maximum output drive current. |
| 3 | GND | power_in | Ground terminal of the device. |
