# UCC27423QDRQ1

**Texas Instruments** · Gate Drivers · SOIC-8

UCC27423QDRQ1 from Texas Instruments, in a SOIC-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 | ENBA | input | Enable input for driver A with logic-compatible threshold and hysteresis, internally pulled up to VDD through 100 kΩ for active-high operation, and the output is low when disabled regardless of the input state. |
| 2 | INA | input | Input signal for driver A with logic-compatible threshold and hysteresis, which must be tied to VDD or GND if unused and must not be left floating. |
| 3 | GND | power_in | Common ground that must be connected very closely to the source of the power MOSFET being driven. |
| 4 | INB | input | Input signal for driver B with logic-compatible threshold and hysteresis, which must be tied to VDD or GND if unused and must not be left floating. |
| 5 | OUTB | output | Driver output B, capable of providing 4-A drive current to the gate of a power MOSFET. |
| 6 | VDD | power_in | Supply voltage and power input connection for this device. |
| 7 | OUTA | output | Driver output A, capable of providing 4-A drive current to the gate of a power MOSFET. |
| 8 | ENBB | input | Enable input for driver B with logic-compatible threshold and hysteresis, internally pulled up to VDD through 100 kΩ for active-high operation, and the output is low when disabled regardless of the input state. |
