MGH201C1E3

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.
