KTM1331MC-ST3
CONNTEK · Hall Switches · SOT-23-3L
KTM1331MC-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; the datasheet gives an operating supply range of 1.8 V to 5.5 V, with an absolute maximum of 6 V and a reverse supply limit of -0.3 V, and a 100 nF capacitor placed close to this pin is recommended for filtering. |
| 2 | OUTPUT | output | Switch output that goes low when the magnetic field exceeds BOP and high when it falls below BRP, with a maximum output drive current of 5 mA. |
| 3 | GND | power_in | Ground pin. |
