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 | GND | power_in | Chip ground. Return for the internal control logic and driver, and source of the internal power MOSFET (floating-ground / GP7596X pinout variant). |+| 2 | GND | power_in | Chip ground. Tied internally to pins 1 and 3; parallel these pins to the ground plane to reduce inductance to the MOSFET source. |+| 3 | GND | power_in | Chip ground. Tied internally to pins 1 and 2. |+| 4 | VCC | power_in | Chip supply pin, nominally 5 V (UVLO on 3.7 V, UVLO off 2.8 V, internally clamped to 6 V at 20 mA). Place a bypass capacitor (typ. 1 µF) close to this pin; the internal HV LDO charges VCC from SW/SWS so no auxiliary winding is needed. |+| 5 | SW | power_out | Drain of the integrated synchronous-rectifier power MOSFET. Operating drain-source voltage rated to 65 V (recommended 4.7-60 V); RDS(on) 18 mΩ for the GP7596A. Tie pins 5-8 in parallel to carry the SR current with minimum resistance. |+| 6 | SW | power_out | Drain of the integrated power MOSFET. Tied internally to pins 5, 7, 8. |+| 7 | SW | power_out | Drain of the integrated power MOSFET. Tied internally to pins 5, 6, 8. |+| 8 | SW | power_out | Drain of the integrated power MOSFET. Tied internally to pins 5, 6, 7. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HaloChip |+| Package | SOP-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `GP7596A`+- `GP7596AA`+- `GP7596AB`+- `GP7596B`+- `GP7596BA`+- `GP7596BB`+- `GP7596C`+- `GP7596CA`+- `GP7596CB`++## CAD (KiCad official)++- Symbol: `GP7596A`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HaloChip datasheet](docs/gp7596a-datasheet.pdf) (7 pp, sha256 `c7e9e6914030b64f`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
