Product details
Overview
UCC5350MCD from Texas Instruments is a single-channel isolated gate driver with Miller-clamp functionality, designed to drive SiC MOSFETs and IGBTs in high-voltage power stages. It delivers 10 A peak source/sink current, features 60 ns typical propagation delay, supports up to 33 V driver supply, and operates across –40°C to +125°C ambient temperature - enabling robust switching control in motor drives and solar inverters.
For engineers reviewing the UCC5350MCD datasheet, UCC5350MCD pinout, UCC5350MCD application, or UCC5350MCD equivalent, this page provides verified technical context, package mapping, isolation certification details, real-world use scenarios, and validated alternative options for industrial power module design.
Technical Context
The UCC5350MCD implements galvanic isolation via capacitive barrier with >40-year lifetime and 100 kV/µs CMTI. Its internal Miller clamp actively pulls the gate to VEE2 during turn-off to suppress false turn-on caused by dv/dt-induced displacement current in fast-switching wide-bandgap devices.
It uses CMOS-compatible inputs referenced to GND1 and outputs referenced to GND2/VEE2, with UVLO2 tied to GND2 for accurate under-voltage detection at the power device emitter. The D-package variant provides 4 mm creepage and 3 kVRMS isolation rating per UL 1577 and DIN V VDE V 0884-11.

Pinout & Package
The UCC5350MCD is housed in an 8-pin SOIC (D package) with 4 mm creepage and reinforced internal insulation barrier. Pin numbering follows standard SOIC-8 top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| IN+ | Noninverting input | CMOS-threshold control signal; pulled low internally if left open |
| IN– | Inverting input | CMOS-threshold complementary control; pulled high internally if left open |
| GND1 | Input ground reference | Reference node for all input-side signals and VCC1 return path |
| VCC2 | Output-side positive supply | High-side gate-drive rail; decouple to VEE2 with 1 µF low-ESR capacitor |
| CLAMP | Miller-clamp output terminal | Active low-impedance path to VEE2 during turn-off to prevent spurious conduction |
| OUT | Main gate-drive output | Single-ended output driving gate-to-emitter/source; connects to power device gate |
| VEE2 | Output-side negative supply | Return for gate-drive output; tied to GND for S/M versions, used as bipolar rail for E version |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Miller Clamp | Clamps gate to VEE2 at ≤10 mV threshold with 10 A sink capability - eliminates need for external clamping diodes in SiC designs |
| High CMTI | 100 kV/µs minimum - maintains signal integrity across isolation barrier during fast transient events in high-power converters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC5350MC | DWV package with 8.5 mm creepage and 5000 VRMS isolation; same electrical specs and Miller clamp | Required where higher working voltage (1500 VRMS) or reinforced insulation per IEC 62368-1 is mandated | Select UCC5350MC when board-level clearance/creepage constraints demand ≥8.5 mm spacing or UL 5000 VRMS certification |
| UCC5320SC | Split-output architecture (OUTH/OUTL), 4.3 A/4.4 A drive, no Miller clamp, 12 V UVLO | Used where independent control of rise/fall times is needed - e.g., optimizing EMI in resonant LLC converters | Choose UCC5320SC only when precise slew-rate tuning is prioritized over Miller-induced false turn-on suppression |
Compared with UCC5350MCD, UCC5350MC offers higher isolation voltage in a larger package for safety-critical systems, while UCC5320SC trades clamp functionality for independent high/low-side output control - making UCC5350MCD optimal for SiC/IGBT applications where dv/dt immunity is paramount.
