EG41A from EG Micro, 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 pin, with an input voltage range of 4V to 35V stated by the datasheet. |
| 2 | GND | power_in | Chip ground terminal. |
| 3 | OUT | output | Open-collector driver output that switches low when B exceeds Bop from the S pole and switches high when B falls below Brp from the N pole on the Marking face, with a sink capability of 40mA. |
