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 | Device ground reference. Common return for the internal shunt regulator, bandgap reference, and D+/D- circuitry. |+| 2 | V1 | output | Open-drain output (switch N1) of the output-voltage adjustment logic. Pulled low when 9 V, 12 V, or 20 V output is requested. RDS(on) typ 300 Ω; drives an external feedback resistor to adjust the adapter's output. Absolute max V1 <= VBP; I(V1) <= 0.5 mA. |+| 3 | V2 | output | Open-drain output (switch N2) of the output-voltage adjustment logic. Pulled low when 12 V or 20 V output is requested. RDS(on) typ 300 Ω. Absolute max V2 <= VBP; I(V2) <= 0.5 mA. |+| 4 | V3 | output | Open-drain output (switch N3) of the output-voltage adjustment logic. Pulled low when 20 V output is requested. Tie V3 to BP (directly or through <=100 kΩ) to inhibit Class-B 20 V operation. RDS(on) typ 300 Ω. |+| 5 | D- | bidirectional | USB D- data line. Monitored during Quick Charge 2.0 handshake and driven low through an internal 19.53 kΩ pull-down (switch N4) plus short-circuited to D+ via N5 during BC1.2 DCP handshake. Absolute max 5 V; I <= 1 mA. |+| 6 | D+ | bidirectional | USB D+ data line. Monitored to detect QC2.0-capable powered devices (VDAT(REF) typ 0.325 V, VSEL(REF) typ 2 V) and receive output-voltage selection commands. Short-circuited to D- via switch N5 in default 5 V mode for BC1.2 DCP handshake. Absolute max 5 V; I <= 1 mA. |+| 7 | R | passive | Reference-current programming pin connected to the internal bandgap (VR typ 1.27 V). Connect an external resistor RREF (recommended 127 kΩ) to GND to set the reference current for internal timing circuits. |+| 8 | BP | power_in | Bypass / internal-supply pin. An internal shunt regulator clamps BP at ~6 V (typ 5.3 V shunt at 3 mA); power the device through an external series resistor (recommended RBP = 4.7 kΩ) from the adapter output and decouple with CBP = 220 nF to GND. Absolute max 5.6 V; IBP max 15 mA. Power-up reset at VBP < 3.9 V; correct operation requires VBP >= 4 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Seaward Elec |+| Package | SOP-8-150mil |+| Category | PMIC |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `SE100-HF`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8-150mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Seaward Elec datasheet](docs/se100-hf-datasheet.pdf) (9 pp, sha256 `917f1584d4636b82`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
