UCC5350MCDR

Texas Instruments · Isolators - Gate Drivers · SOIC-8

UCC5350MCDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC1 power_in Input-side supply voltage (3 V to 15 V). Connect a locally decoupled capacitor to GND1. Use a low-ESR/ESL capacitor located as close to the device as possible.
2 IN+ input Noninverting gate-drive voltage-control input with CMOS input threshold. Pulled low internally if left open. Together with IN- defines the output logic state.
3 IN- input Inverting gate-drive voltage-control input with CMOS input threshold. Pulled high internally if left open. Together with IN+ defines the output logic state.
4 GND1 power_in Input-side (primary) ground reference. All input-side signals (VCC1, IN+, IN-) are referenced to this ground.
5 VCC2 power_in Positive output-side (secondary) supply rail (13.2 V to 33 V nominal for UCC5350M). Connect a locally decoupled low-ESR/ESL capacitor to VEE2 close to the device.
6 OUT output Gate-drive output for the UCC53x0M variant. Provides 5-A peak source and 5-A peak sink current to drive the gate of an external power MOSFET/IGBT/SiC/GaN device.
7 CLAMP input Active Miller-clamp input found on the UCC53x0M variant. Used to prevent false turn-on of the power switch caused by Miller current during high dV/dt events.
8 VEE2 power_in Negative output-side supply rail; also the output-side ground reference for S and M versions. Connect a locally decoupled low-ESR/ESL capacitor to VCC2 close to the device.

Same part, different packaging or reel option.

  • UCC5350MCDR
  • UCC5350MCDWV

CAD (KiCad official)

  • Symbol: UCC5350MCDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ucc5350mcdr-etched.step / ucc5350mcdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ucc5350mcdr.step / ucc5350mcdr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ucc5350mcdr.step 122 KB You want the bare part, or you mark your own boards.
ucc5350mcdr-etched.step 2.6 MB You want the part with UCC5350MCDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 616 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
