# UCC27511ADBVT

**Texas Instruments** · Gate Drivers · SOT-23-6

UCC27511ADBVT from Texas Instruments, in a SOT-23-6. 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 | VDD | power_in | Bias supply input for the driver; the datasheet's recommended supply range is 4.5 V to 18 V. |
| 2 | OUTH | output | Sourcing current output of the driver; connect a resistor between OUTH and the power-switch gate to adjust turn-on speed. |
| 3 | OUTL | output | Sinking current output of the driver; connect a resistor between OUTL and the power-switch gate to adjust turn-off speed. |
| 4 | GND | power_in | Ground; all signals are referenced to this pin. |
| 5 | IN- | input | Inverting input; for non-inverting use connect IN- to GND to enable the output, and connect IN- to VDD or leave it floating to disable the output. |
| 6 | IN+ | input | Non-inverting input; for inverting use connect IN+ to VDD to enable the output, and connect IN+ to GND or leave it floating to disable the output. |
