DS28E05R+T from Analog Devices Inc Maxim Integrated, in a SOT-23-3. 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 | IO | bidirectional | 1-Wire bus interface: open-drain signal that requires an external pullup resistor (max 1.5kΩ at 3.3V VPUP, max 750Ω at 1.8V VPUP per the datasheet). |
| 2 | N.C. | unconnected | Not connected. |
| 3 | GND | power_in | Ground reference for the 1-Wire bus and device. |
