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, open-drain reset output. Pulled low while VCC is below the 2.93V reset threshold (VRES). After VCC rises above VRES+VHYST (VHYST = 0.013 x VRES), the pin is held low for at least 140 ms (typ 240 ms, max 400 ms) and then goes high-impedance. VOL <= 0.3V at ISINK = 3.2 mA (VCC = 3V). Requires an external pull-up resistor. |+| 3 | VCC | power_in | Positive supply input and the voltage being monitored. Operating range 1.15V to 5.5V (abs max 6.0V). Typical IVCC = 3.2 uA at 3V. A 0.1 uF bypass capacitor to GND near this pin improves rejection of short VCC glitches. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ShangHai Consonance Elec |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `CN803S`++## CAD (KiCad official)++- Symbol: `CN803S`+- 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 Consonance Elec datasheet](docs/cn803s-datasheet.pdf) (7 pp, sha256 `4105c79299e10a52`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
