Asserts low whenever VDD falls below the internal 2.9 V threshold and remains asserted for a 220 ms delay after VDD recovers above VTH. Requires an external pull-up (e.g. 100 kΩ to VDD); VOL < 0.4 V at ISINK > 3.5 mA. |+| 2 | GND | power_in | Ground reference for the device. |+| 3 | VDD | power_in | Supply/monitor input. Operating range 0.9 V to 6 V (absolute max -0.3 V to 6 V). Also the voltage sensed against the internal 2.9 V reset threshold (VTH tolerance ±1.5%). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Richtek Tech |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `RT9818C-29GVV`+- `RT9818C-29GVVL`+- `RT9818C-29GVU3`+- `RT9818C-29GVB`+- `RT9818C-29GVX`+- `RT9818C-29GVY`+- `RT9818C-29GVYR`++## CAD (KiCad official)++- Symbol: `RT9818C-29GV`+- 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:** [Richtek Tech datasheet](docs/rt9818c-29gv-datasheet.pdf) (14 pp, sha256 `3b9d0defd96dfd4a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
