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 device. |+| 2 | RESET | output | Active-low CMOS reset output. Driven low while VCC is below the 2.63V reset threshold (VRES) and held low for at least 140 ms (typ 240 ms) after VCC rises above VRES+VHYST (VHYST ≈ 0.013×VRES), then transitions high. Sinks up to 3.2 mA at VCC=3V while maintaining VOL ≤ 0.3V; sources ≥1.2 mA at VCC=3V while maintaining VOH ≥ VCC-0.4V. |+| 3 | VCC | power_in | Positive supply input. This pin both powers the internal circuitry and is the voltage being monitored against the reset threshold. Absolute max 6.0V; operating range up to 5.5V; valid reset output guaranteed down to 1.15V. A 0.1µF bypass capacitor close to this pin is recommended to improve short-glitch filtering. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `CN809R`++## CAD (KiCad official)++- Symbol: `CN809R`+- 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:** [ShangHai Consonance Elec datasheet](docs/cn809r-datasheet.pdf) (7 pp, sha256 `bbeb80fd1a0c3663`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
