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 | Ground reference pin (Vss). Connect to system ground. |+| 2 | VIN | power_in | Input supply / monitored voltage pin. Operating range 1.2V to 7.5V; absolute maximum 8.0V. This is the voltage that the detector compares against the internal VDET threshold (3.08V typ for the C308 variant). |+| 3 | Vout/Reset | output | CMOS push-pull reset output. Driven low when VIN falls below VDET (3.08V typ), and held low for a 200ms active timeout period after VIN recovers above threshold. No external pull-up required for the 'C' (CMOS) variant. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Shanghai Siproin Microelectronics |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `SSP809C308NRC263`+- `SSP809C308NRC293`+- `SSP809C308NRC308`+- `SSP809C308NRC400`+- `SSP809C308NRC438`+- `SSP809C308NRN263`+- `SSP809C308NRN293`+- `SSP809C308NRN308`+- `SSP809C308NRN400`+- `SSP809C308NRN438`++## CAD (KiCad official)++- Symbol: `SSP809C308NR`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Shanghai Siproin Microelectronics datasheet](docs/ssp809c308nr-datasheet.pdf) (7 pp, sha256 `0ca8af4133e9fda5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
