# GBI7256NMCR

**GOSEMICON** · Gate Drivers · WSON-8-EP(3x3)

GBI7256NMCR from GOSEMICON, in a WSON-8-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INA- | input | Channel A inverting input; tie to GND to enable Channel A output in non-inverting configuration, and OUTA is held low if INA- is floating or biased high. Input voltage range is -5 V to 20 V. |
| 2 | INB- | input | Channel B inverting input; tie to GND to enable Channel B output in non-inverting configuration, and OUTB is held low if INB- is floating or biased high. Input voltage range is -5 V to 20 V. |
| 3 | GND | power_in | Power ground for the device. |
| 4 | OUTB | output | Channel B gate driver output, rated 5 A peak source and sink current with output voltage limits of -0.3 V to 22 V. |
| 5 | VDD | power_in | System power supply; operating range 4.5 V to 20 V, absolute maximum -0.3 V to 22 V, with input UVLO rising threshold of 4.2 V typical. |
| 6 | OUTA | output | Channel A gate driver output, rated 5 A peak source and sink current with output voltage limits of -0.3 V to 22 V. |
| 7 | INB+ | input | Channel B non-inverting input; tie high to enable Channel B output in inverting configuration, and OUTB is held low if INB+ is floating or biased low. Input voltage range is -5 V to 20 V. |
| 8 | INA+ | input | Channel A non-inverting input; tie high to enable Channel A output in inverting configuration, and OUTA is held low if INA+ is floating or biased low. Input voltage range is -5 V to 20 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
