SM2082ED from Shenzhen Sunmoon Micro, in a SOP-8-EP. 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 | Ground reference for constant-current channel 1. |
| 2 | REXT1 | passive | Output current setting pin for channel 1; the output current is I_OUT = 0.6 V / Rext, adjustable from 5 mA to 60 mA by an external resistor. |
| 3 | GND2 | power_in | Ground reference for constant-current channel 2. |
| 4 | REXT2 | passive | Output current setting pin for channel 2; the output current is I_OUT = 0.6 V / Rext, adjustable from 5 mA to 60 mA by an external resistor. |
| 5 | OUT2 | power_in | Power input and constant-current output port for channel 2; absolute OUT voltage range is -0.5 V to +450 V, and the OUT voltage must stay above VOUT_MIN (max 6.5 V at IOUT = 30 mA) for proper regulation. |
| 6 | NC | unconnected | No-connect pin, left floating. |
| 7 | OUT1 | power_in | Power input and constant-current output port for channel 1; absolute OUT voltage range is -0.5 V to +450 V, and the OUT voltage must stay above VOUT_MIN (max 6.5 V at IOUT = 30 mA) for proper regulation. |
| 8 | NC | unconnected | No-connect pin, left floating. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
