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

TPSI3052DWZR 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 | EN | input | Active high driver enable; 0-5.5 V in three-wire mode or 0-48 V in two-wire mode |
| 2 | PXFR | input | Power transfer control via external resistor to VSSP selecting one of seven power levels; 0-5.5 V |
| 3 | VDDP | power_in | Primary side power supply; 3.0-5.5 V in three-wire mode or 6.5-48 V in two-wire mode |
| 4 | VSSP | power_in | Primary side ground reference |
| 5 | VSSS | power_in | Secondary side ground reference |
| 6 | VDDM | power_out | Generated mid-level supply output for secondary side bias |
| 7 | VDDH | power_out | Generated high supply output; 15 V nominal for gate drive power |
| 8 | VDRV | output | Active high driver output; 15 V nominal with 1.5/3.0-A peak source and sink current |
