Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | Vin | power_in | Positive input voltage to the device. Continuous rating 30 V, non-repetitive peak 60 V (t <= 1 ms). Supplies the internal current-source control circuit and the LED string via the external Rext. |+| 2 | Boost | output | Optional boost pin used to drive an external transistor for higher current or PWM operation, as described in ON Semi App Note AND8198/D. Left unconnected in the basic LED-driver configuration (the package soldering-footprint sheet labels this pin as N/C). |+| 3 | Rext | passive | External current-set resistor pin. A resistor connected between Rext and Vin programs the LED drive current (Iout = Vsense / Rext, e.g. Rext = 2.0 ohm gives ~325 mA at 12 V in). See Figure 1 for Rext vs Iout. |+| 4 | GND | power_in | Device ground reference for the internal current-source control circuitry. |+| 5 | Iout | output | Regulated LED current output. Cathode(s) of the driven LED string connect from this pin to ground. Rated up to 500 mA (with Vdrop <= 2.2 V); Vout max 28 V. Pins 5-8 are tied internally to the same current-source output and are typically paralleled. |+| 6 | Iout | output | Regulated LED current output (internally common with pins 5, 7, 8). Connect LED cathode(s) from this pin to ground. Parallel pins 5-8 to spread current and improve thermal performance. |+| 7 | Iout | output | Regulated LED current output (internally common with pins 5, 6, 8). Connect LED cathode(s) from this pin to ground. |+| 8 | Iout | output | Regulated LED current output (internally common with pins 5, 6, 7). Connect LED cathode(s) from this pin to ground. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | LED-drv |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `NUD4001DR2G`+- `NUD4001DR2GNSVD4001DR2G`++## CAD (KiCad official)++- Symbol: `NUD4001DR2G`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/nud4001-d.pdf) (8 pp, sha256 `385fc571e81f6ce3`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
