**GoChip Elec Tech Shanghai** · Hall Switches · TO-92S

GH41F045-B2 from GoChip Elec Tech Shanghai, 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 | VCC | power_in | Supply voltage input, operating range 3.8V to 30V (absolute maximum -30V to +40V). |
| 2 | GND | power_in | Ground. |
| 3 | VOUT | output | Open-collector output that requires an external pull-up resistor, sinking up to 40mA (IOL max) with VOL of 100-250mV at 25mA. |
