# UCC27524DSDR

**Texas Instruments** · Gate Drivers · SON-8-EP(3x3)

UCC27524DSDR from Texas Instruments, in a SON-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 | ENA | input | Channel A enable input; low disables output, high or floating enables output. |
| 2 | INA | input | Channel A non-inverting input; keeps OUTA low when floating. |
| 3 | GND | power_in | Ground reference for all signals. |
| 4 | INB | input | Channel B non-inverting input; keeps OUTB low when floating. |
| 5 | OUTB | output | Channel B output. |
| 6 | VDD | power_in | Auxiliary power supply input, 4.5V to 18V rated. |
| 7 | OUTA | output | Channel A output. |
| 8 | ENB | input | Channel B enable input; low disables output, high or floating enables output. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
