# UCC5320SCDR

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

UCC5320SCDR 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 | VCC1 | power_in | Input supply voltage (3V to 15V range) for input stage logic; bypass to GND with low ESR/ESL capacitor. |
| 2 | IN+ | input | Non-inverting gate drive control input with CMOS threshold; internally pulled low when left open circuit. |
| 3 | IN- | input | Inverting gate drive control input with CMOS threshold; internally pulled high when left open circuit. |
| 4 | GND1 | power_in | Input stage ground reference for all input-side signals. |
| 5 | VCC2 | power_in | Output stage positive supply (13.2V to 33V) for gate driver output stage; bypass to VEE2 with low ESR/ESL capacitor. |
| 6 | OUTH | output | Upper gate drive pull-up output with 4.3A typical source current on UCC5320S. |
| 7 | OUTL | output | Lower gate drive pull-down output with 4.4A typical sink current on UCC5320S. |
| 8 | VEE2 | power_in | Output stage negative supply/ground for S and M versions; bypass with low ESR/ESL capacitor. |
