# GT4426DTR

**XBLW** · Gate Drivers · SOP-8

GT4426DTR from XBLW, in a SOP-8. 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 | NC | unconnected | No internal connection. |
| 2 | INA | input | Input A for channel A driver; logic input range -10 V to Vcc+0.3 V, output is inverted. |
| 3 | GND | power_in | Ground; tolerates up to 5 V of noise spiking on the ground pin. |
| 4 | INB | input | Input B for channel B driver; logic input range -10 V to Vcc+0.3 V, output is inverted. |
| 5 | OUTB | output | Output B (inverting) with 2 A peak current; withstands 500 mA reverse current. |
| 6 | VCC | power_in | Power supply, 4.5 V to 20 V recommended operating range (25 V absolute maximum). |
| 7 | OUTA | output | Output A (inverting) with 2 A peak current; withstands 500 mA reverse current. |
| 8 | NC | unconnected | No internal connection. |
