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 | SOURCE1 | power_out | Source of channel 1 power MOSFET. Typically tied to the load return / low-side node; current returns through this pin. Reverse DC output current rating -3 A. |+| 2 | INPUT1 | bidirectional | Control / diagnostic pin for channel 1. Drives the internal gate control block (VINTH 0.5-2.5 V, IIN limited to ±20 mA, RIN min 330 Ω required externally, ISS ~100 µA at VIN=5 V). Also acts as fault feedback: when overtemperature / short circuit occurs the pin is pulled to a fault sink current (Igf ≈ 10-20 mA) which can be monitored. |+| 3 | SOURCE2 | power_out | Source of channel 2 power MOSFET. Independent from SOURCE1. Reverse DC output current rating -3 A. |+| 4 | INPUT2 | bidirectional | Control / diagnostic pin for channel 2. Same behavior as INPUT1: drives the gate control, requires ≥330 Ω series impedance, VINTH 0.5-2.5 V, and reports faults by sinking Igf ≈ 10-20 mA when protection trips. |+| 5 | DRAIN2 | power_in | Drain of channel 2 power MOSFET (paralleled with pin 6 for current handling and thermal). Connected to the supply / high-side node. Drain-source clamp voltage 40 V (typ 45 V). |+| 6 | DRAIN2 | power_in | Drain of channel 2 power MOSFET (paralleled internally with pin 5). Provides additional current and heat-sinking capability; tie both pins together on the PCB. |+| 7 | DRAIN1 | power_in | Drain of channel 1 power MOSFET (paralleled with pin 8). Connected to the supply / high-side node. Drain-source clamp voltage 40 V (typ 45 V). |+| 8 | DRAIN1 | power_in | Drain of channel 1 power MOSFET (paralleled internally with pin 7). Tie both pins together on the PCB for full current and thermal capability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SO-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `VNS1NV04DPTR-EVNS1NV04DP-E (tube)`+- `VNS1NV04DPTR-E (tape and reel)`++## CAD (KiCad official)++- Symbol: `VNS1NV04DPTR-E`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SO-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/vns1nv04dptr-e.pdf) (24 pp, sha256 `f7d7cba484b36f86`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
