Hallwee · Hall Switches · TO-92S

TMR2301AHUA from Hallwee, 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, specified for operation from 1.8 V to 5.5 V, with an absolute maximum VDD of 6 V and a reverse supply limit of -0.3 V.
2	Gnd	power_in	Ground pin, the supply return for the device.
3	Out	output	Push-pull CMOS output that goes low when the field exceeds BOP and high when it falls below BRP, with output drive current limited to 5 mA absolute maximum.
