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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `UCC5350MCDR`+- `UCC5350MCDRUCC5350MCDWV`++## CAD (KiCad official)++- Symbol: `UCC5350MCDR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/ucc5350mcdr-datasheet.pdf) (60 pp, sha256 `798d0abc35823333`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
