GX1822 from GXCAS, in a TO-92. 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 | GND | power_in | Ground pin for the GX1822, the reference for all voltages (absolute pin-to-ground range -0.5V to +6.0V). |
| 2 | DQ | bidirectional | Open-drain 1-Wire data input/output that needs an external pull-up (about 4.7kΩ to 5kΩ) and also supplies the chip in parasite-power mode. |
| 3 | VDD | power_in | External supply pin, operating from 2.5V to 5.5V; it must be connected to GND when the device is parasite-powered. |
