Pinout and pin descriptions extracted from the datasheet (via LCSC) by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | GND | power_in | Ground pin. 0 V reference for VDD and the RESET output driver. |+| 2 | RESET | output | Active-low reset output. RESET is driven low when VDD is below the reset threshold voltage (typ. 2.63 V for MAX809R) and returns high after at least ~140-150 ms delay once VDD rises back above threshold. Maximum output current 20 mA; push-pull driver referenced to VDD. |+| 3 | VDD | power_in | Chip power supply and monitored voltage input. Operating range 1.0 V to 5.5 V, absolute max +6.0 V. Typical supply current 8-14 uA. This is the voltage sensed against the internal reset threshold. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW Youtai Semiconductor Co   Ltd |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `MAX809R`+- `MAX809R`++## CAD (KiCad official)++- Symbol: `MAX809R`+- 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:** [UMW Youtai Semiconductor Co   Ltd datasheet](https://datasheet.lcsc.com/datasheet/pdf/0e8e5426beae08c6f384ad5a32bf2b8b.pdf) (12 pp, sha256 `0fbe59798e7e2e41`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
