Slkor SLKORMICRO Elec · Hall Switches · SOT-23
SL44E-3 from Slkor SLKORMICRO Elec, in a SOT-23. 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 | VSUP | power_in | Supply pin for the sensor, specified for 3.8 V to 40 V operation with an absolute maximum VDD of 60 V. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | VOUT | output | Open-collector output that requires an external pull-up resistor, with output sink current rated at 30 mA (absolute maximum 40 mA) and output voltage absolute maximum of 60 V. |
