**Megain** · Hall Switches · TO-92S

MGH201C1E3 from Megain, in a TO-92S. 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 voltage pin; the datasheet specifies an operating range of 3.5V to 30V VDD, with a 100nF bypass capacitor placed as close as possible between VDD and GND. |
| 2 | GND | power_in | Ground pin; the 100nF VDD-to-GND bypass capacitor should be placed as close to the device as possible. |
| 3 | VOUT | output | Open-drain output that is driven low when the magnetic flux exceeds BOP on the marked side, with an output saturation voltage VDSON of 0.5V max at IOUT = 20mA and a maximum output current of 50mA. |
