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 when VCC falls below the 4.00 V reset threshold and held low for at least 140 ms (typ 240 ms, max 400 ms) after VCC rises above VRES+VHYST, then goes high. Drives VOL<=0.3 V at ISINK up to 5 mA and VOH>=VCC-0.4 V at ISRC up to 2.5 mA. |+| 3 | VCC | power_in | Positive supply input; this pin is both the operating supply for the internal circuitry and the monitored voltage. Operating range 1.15 V (min guaranteed output) up to 5.5 V (VCCMAX), absolute max 6.0 V. A 0.1 µF bypass to GND close to this pin is recommended to improve rejection of short supply glitches. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOT-23-3 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `CN809J`++## CAD (KiCad official)++- Symbol: `CN809J`+- 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/cn809j-datasheet.pdf) (7 pp, sha256 `bbeb80fd1a0c3663`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
