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 | Push-pull reset output. Active-low on the APX811: driven low while VCC is below the reset threshold (3.08V typ. for the -31 option) or while MR is held low, and for approximately 200ms after VCC returns above threshold. Guaranteed valid for VCC > 1V; for valid operation down to VCC = 0V, add a ~100k pull-down. |+| 3 | MR | input | Manual reset input, active low. Driving MR low forces RESET active; must be held low at least 100ns (tW) to be recognized. Typically driven by a push-button to GND with a pull-up to VCC. |+| 4 | VCC | power_in | Operating voltage input, monitored supply. Recommended range 1.1V to 5.5V; absolute maximum -0.3V to +7V. Typical supply current is 30uA at VCC = Vth + 0.2V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-143 |+| Category | PMIC |+| Pins | 4 |++## Ordering variants++Same part, different packaging or reel option.++- `APX811-31UG-7`++## CAD (KiCad official)++- Symbol: `APX811-31UG-7`+- Footprint: `Package_TO_SOT_SMD:SOT-143`+- 3D model: SOT-143 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/APX811-31UG-7.pdf) (10 pp, sha256 `7a730fe754bff472`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
