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 | ENA | input | Channel A Enable Input. Biased low disables Channel A output regardless of INA state. Biased high or floating enables Channel A output. Logic threshold ~2.1V typ, absolute max range -5V to 26V. |+| 2 | INA | input | Channel A logic input. Drives OUTA via non-overlap driver. TTL/CMOS compatible with ~1.1V hysteresis. Accepts negative voltage down to -5V for improved noise immunity. |+| 3 | GND | power_in | Power ground return for the device. Common return for both driver channels. |+| 4 | INB | input | Channel B logic input. Drives OUTB via non-overlap driver. TTL/CMOS compatible with ~1.1V hysteresis. Accepts negative voltage down to -5V for improved noise immunity. |+| 5 | OUTB | output | Channel B gate driver output. 5A peak source/sink current with ~10Ω pull-up and ~0.6Ω pull-down resistance. Rise/fall times 8ns/6ns typical into 1nF load. Drives MOSFET/IGBT/GaN gates from GND to VDD. |+| 6 | VDD | power_in | System power supply input. Operating range 4.5V to 24V. UVLO threshold ~4.2V rising with ~300mV hysteresis. Requires local bypass capacitor for peak gate-drive current. |+| 7 | OUTA | output | Channel A gate driver output. 5A peak source/sink current with ~10Ω pull-up and ~0.6Ω pull-down resistance. Rise/fall times 8ns/6ns typical into 1nF load. Drives MOSFET/IGBT/GaN gates from GND to VDD. |+| 8 | ENB | input | Channel B Enable Input. Biased low disables Channel B output regardless of INB state. Biased high or floating enables Channel B output. Logic threshold ~2.1V typ, absolute max range -5V to 26V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GOSEMICON |+| Package | SOIC-8L |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `GBI7254SMBR`+- `GBI7254SMBRGBI7254CSMBR`+- `GBI7254SMBRGBI7254CSMBR`+- `GBI7254SMBRGBI7254MMAR`+- `GBI7254SMBRGBI7254NMCR`++## CAD (KiCad official)++- Symbol: `GBI7254SMBR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GOSEMICON datasheet](docs/gbi7254smbr-datasheet.pdf) (15 pp, sha256 `90e33738e2efc5f0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
