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 for the supervisor. Connect to system ground. |+| 2 | RESET | output | Active-low reset output (RESET-bar). Asserted low when VCC falls below the reset threshold (2.93V typ for MAX809S) and held low for ~200ms after VCC returns above threshold. VOL ≤ 0.3V at ISINK=1.2mA; VOH ≥ 0.8·VCC at ISOURCE=500µA. |+| 3 | VCC | power_in | Supply and monitored input voltage. Operating range 1.0V-6.0V (absolute max 6.5V). ICC ≈ 5.5µA at VCC=6V. The device compares VCC against the internal threshold Vth (2.93V typ for the -S variant). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MSKSEMI |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `MAX809SS`+- `MAX809S`++## CAD (KiCad official)++- Symbol: `MAX809S`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MSKSEMI datasheet](docs/max809s-datasheet.pdf) (6 pp, sha256 `7fc0c8bc22e4d962`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
