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 | passive | Source of channel-1 low-side N-channel MOSFET. Typically tied to system ground (load current return, internally current-sensed for the 3.7-5.0 A current limit). |+| 2 | Gate1 | input | Gate (logic-level input) of channel-1 MOSFET. Analog drive capable; VGS(th) ≈ 1.3-2.2 V, absolute max VGS = ±14 V. Drives the internal N-MOSFET on/off; overvoltage is clamped drain-to-gate for inductive-load protection. |+| 3 | Source2 | passive | Source of channel-2 low-side N-channel MOSFET. Typically tied to system ground; independent from channel-1 source. |+| 4 | Gate2 | input | Gate (logic-level input) of channel-2 MOSFET. Same electrical characteristics as Gate1: VGS(th) ≈ 1.3-2.2 V, VGS max ±14 V, analog drive capable. |+| 5 | Drain2 | passive | Drain of channel-2 MOSFET (connects to the switched load). Internally clamped at 42 V (V(BR)DSS). Bonded to two package pins (5 and 6) to share current and improve thermal conduction - tie both to the load node. |+| 6 | Drain2 | passive | Drain of channel-2 MOSFET (same net as pin 5). Second drain pin provided for current sharing and PCB heat spreading. |+| 7 | Drain1 | passive | Drain of channel-1 MOSFET (connects to the switched load). Internally clamped at 42 V. Bonded to two package pins (7 and 8) for current sharing and thermal dissipation. |+| 8 | Drain1 | passive | Drain of channel-1 MOSFET (same net as pin 7). Second drain pin provided for current sharing and PCB heat spreading. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `NCV8402ADDR2GADDR2G`+- `NCV8402ADDR2GDDR2G`++## CAD (KiCad official)++- Symbol: `NCV8402ADDR2G`+- 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/ncv8402ad-d.pdf) (11 pp, sha256 `c70bb5c67ed1d089`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
