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 | OUT | output | Chip output. NMOS open-drain detector output that pulls low when VDD falls below VDET (typ 3.3 V for HT7033); requires an external pull-up resistor (e.g. Rp in the application circuit). Sink current IOL ≥ 2 mA (typ 4 mA) at VOUT = 0.2 V with VDD = VDET−0.2 V. |+| 3 | VDD | power_in | Chip input / supply. Operating range 1.5 V to 12 V (absolute max 15 V). Also serves as the sensed input for the internal voltage detector. Typical quiescent current IDD ≈ 2 µA (max 4 µA) with no load. |+| 2 | GND | power_in | Chip ground / 0 V reference for the supply and output driver. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SOT-23 |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `HT7033S`+- `HT7033S-1`++## CAD (KiCad official)++- Symbol: `HT7033S`+- 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:** [UMW datasheet](docs/ht7033s-datasheet.pdf) (12 pp, sha256 `ca4a5b03cf717e3e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
