SC2498SO

Semiment · Hall Switches · SOT-23-3

SC2498SO from Semiment, in a SOT-23-3. 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 for the 2.8 to 40 V operating range; the device withstands transients up to 45 V and does not operate between -0.5 V and 2.5 V.
2 OUT output Open-drain NMOS output that requires an external pull-up resistor, may be pulled up to VDD or another voltage (VPULL), and is rated to sink up to 30 mA with output saturation of 500 mV max at 20 mA.
3 GND power_in Ground terminal, the reference for VDD.
