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 pin. Connect to system ground. |+| 2 | RESET | output | Active-low reset output (push-pull). Drives low when VDD falls below the reset threshold (J = 4.00 V typ, 3.92 V min / 4.08 V max at 25 degC). Returns high after VDD recovers above the threshold and the reset timeout (TR, 240 ms typ, 140 ms min) elapses. VOL <= 0.3 V, VOH >= VDD-0.4 V; output current rated up to 20 mA. |+| 3 | VDD | power_in | Chip 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 over 2-5 V. This is the node compared to the internal reference to generate RESET. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `MAX809J`++## CAD (KiCad official)++- Symbol: `MAX809J`+- 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:** [TECH PUBLIC datasheet](docs/max809j-datasheet.pdf) (7 pp, sha256 `bf42717802d474fe`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
