# GBI7254SMBR

**GOSEMICON** · Isolators - Gate Drivers · SOIC-8L

GBI7254SMBR from GOSEMICON, in a SOIC-8L. 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. |
