DX2082EGS from Dersem, in a ESOP-8. 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 | GND1 | power_in | Chip 1 ground pin. |
| 2 | REXT1 | passive | Output current setting pin; external Rext sets IOUT = 0.6V/Rext, with VREXT typically 0.6V and IOUT range 5mA to 100mA. |
| 3 | NC | unconnected | No connection, left floating. |
| 4 | NC | unconnected | No connection, left floating. |
| 5 | NC | unconnected | No connection, left floating. |
| 6 | NC | unconnected | No connection, left floating. |
| 7 | OUT1 | power_in | Chip 1 power input and constant-current output port; voltage rated -0.5V to 500V, current 5mA to 100mA. |
| 8 | NC | unconnected | No connection, left floating. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
