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 | VOUT | power_out | Regulated output voltage (typ 5V, 4.8V-5.2V). Bypass with a low-ESR ceramic capacitor of at least 10μF placed as close to the pin as possible. Rated for up to 250mA (VIN=4.5V); short-circuit current limits to ~300mA. |+| 2 | GND | power_in | Ground return. Tie to a solid ground plane for best performance and thermal dissipation. |+| 3 | EN | input | Enable / shutdown input, active high (CMOS input, threshold ~0.8V). Drive high to enable the charge pump; drive low to enter shutdown (<1μA). Must not be left floating. Absolute max -0.3V to 6V. |+| 4 | C- | passive | Flying capacitor negative terminal. Connect to the negative side of the external flying capacitor (≥2.2μF low-ESR ceramic; never polarized). Do not load this pin. |+| 5 | VIN | power_in | Input supply voltage, 2.7V to 5V (absolute max 6V). Bypass with a low-ESR ceramic capacitor of at least 10μF placed as close to the pin as possible. |+| 6 | C+ | passive | Flying capacitor positive terminal. Connect to the positive side of the external flying capacitor (≥2.2μF low-ESR ceramic; never polarized). Do not load this pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HEXIN |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## CAD (KiCad official)++- Symbol: `HX4002-MFC`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HEXIN datasheet](docs/hx4002-mfc-datasheet.pdf) (10 pp, sha256 `08fea31a4ad7d1e0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
