Product details
Overview
UCC5350SBD from Texas Instruments is a single-channel, isolated gate driver with split outputs (OUTH/OUTL), designed to drive SiC MOSFETs and GaN FETs in high-efficiency power stages. It delivers 8.5 A source / 10 A sink peak current, features 8 V UVLO on the output side (VCC2–VEE2), supports up to 33 V driver supply, and achieves 60 ns typical propagation delay with ≥100 kV/µs CMTI.
For engineers reviewing the UCC5350SBD datasheet, UCC5350SBD pinout, UCC5350SBD application, or UCC5350SBD equivalent, this page provides verified functional specifications, SOIC-8 (D package) pin mapping, safety-certified isolation parameters, and validated alternatives for motor drives, solar inverters, and EV power modules.
Technical Context
The UCC5350SBD implements galvanic isolation via capacitive barrier with reinforced insulation (4242 VPK, 3000 VRMS per UL 1577), enabling safe operation between input logic (GND1-referenced) and high-side gate-drive circuitry (VCC2/VEE2-referenced). Its split-output architecture independently controls turn-on (OUTH) and turn-off (OUTL) paths to optimize switching timing and reduce Miller-induced false turn-on.
UVLO2 is referenced to VEE2 (not GND2), providing accurate under-voltage detection across bipolar output rails. The device operates from –40°C to +125°C ambient and integrates CMOS-compatible inputs with internal pull-down (IN+) and pull-up (IN–) to ensure defined states during floating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Configuration | Split output (OUTH and OUTL) enables independent rise/fall time control for precise gate timing. |
| Peak Source/Sink Current | 8.5 A / 10 A - sufficient to rapidly charge/discharge high-Qg SiC/GaN gates without external buffers. |
| Propagation Delay | 60 ns typical - reduces timing uncertainty in high-frequency (>100 kHz) power converters. |
| CMTI | ≥100 kV/µs - maintains signal integrity in noisy high-dV/dt environments like motor drives and inverters. |
| UVLO2 Threshold | 8.7 V (rising), 7.3 V (falling) - tight 1.4 V hysteresis prevents oscillation during brownout recovery. |
| Isolation Rating | 4242 VPK transient, 3000 VRMS for 1 min - certified to DIN V VDE V 0884-11:2017-01 and UL 1577. |
| Operating Temperature | –40°C to +125°C - supports placement near power semiconductors in industrial and automotive thermal zones. |
Pinout & Package
UCC5350SBD is housed in an 8-pin SOIC package (D package, 4 mm creepage), compliant with IPC-7351B standard MS-012AC. Creepage and clearance meet IEC 60664-1 requirements for basic insulation at ≤150 VRMS mains voltage.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 | Input-side power supply | 3–15 V logic-side bias; powers internal level shifter and control logic; requires local 0.1 µF decoupling to GND1. |
| IN+ | Non-inverting input | CMOS threshold (0.55×VCC1); pulled low internally if open; defines active-high gate enable path. |
| IN– | Inverting input | CMOS threshold (0.3×VCC1); pulled high internally if open; enables differential or single-ended operation. |
| GND1 | Input ground reference | Reference node for all input signals and VCC1; must be isolated from power ground. |
| VCC2 | Positive output supply rail | 13.2–33 V gate-drive supply; referenced to VEE2; requires local 1 µF decoupling to VEE2. |
| OUTH | High-side gate drive output | Active pull-up path for turn-on; delivers 8.5 A peak source current into gate capacitance. |
| OUTL | Low-side gate drive output | Active pull-down path for turn-off; delivers 10 A peak sink current; minimizes Miller plateau duration. |
| VEE2 | Negative output supply rail | Bipolar gate-drive return; supports negative voltage bias (e.g., –5 V) to enhance noise immunity and prevent shoot-through. |
Key Features
| Feature | Design Value |
|---|---|
| Split Output Architecture | Independent OUTH and OUTL outputs allow asymmetric gate resistor selection to tune dV/dt and EMI without compromising switching speed. |
| 8 V UVLO2 with VEE2 Reference | Accurate under-voltage lockout tied directly to the output rail's negative terminal ensures reliable gate drive disable during VCC2 collapse or VEE2 drift. |
| 100 kV/µs CMTI | Robust common-mode noise rejection prevents false triggering in high-power half-bridge and three-phase inverter legs. |
| 4242 VPK Transient Isolation | Validated surge withstand capability meets IEC 62368-1 requirements for industrial equipment with high-energy transients. |
| –40°C to +125°C Operation | Full-rated performance across extended temperature range eliminates derating in compact, thermally constrained power modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC5350SB | Same SOIC-8 (D) package, identical 8.5 A/10 A drive strength and 8 V UVLO2, but lacks VEE2 pin - uses GND2 instead. | Not suitable for bipolar gate-drive configurations requiring negative voltage bias on the output side. | Select UCC5350SB only when VEE2 = GND2 and unipolar gate drive suffices. |
| UCC5390SC | Higher 17 A/17 A drive strength, same split-output topology and SOIC-8 (D) footprint, but uses 12 V UVLO2 and no VEE2 pin. | Targeted at higher-current IGBT/SiC modules where gate charge exceeds 100 nC; not rated for negative VEE2 operation. | Choose UCC5390SC when driving large discrete devices or paralleled modules needing >10 A peak current. |
Compared with UCC5350SB and UCC5390SC, the UCC5350SBD uniquely supports true bipolar gate bias (VCC2–VEE2) with VEE2-referenced UVLO2, making it the only option among the three for designs requiring negative gate voltage to suppress Miller turn-on in high-dV/dt SiC/GaN applications.

FAQ
What is the maximum recommended driver supply voltage for UCC5350SBD?
The UCC5350SBD supports a total output-side supply voltage (VCC2 – VEE2) up to 33 V, with minimum operating voltage of 9.5 V. This range accommodates both unipolar (e.g., 15 V/0 V) and bipolar (e.g., 15 V/–5 V) gate-drive configurations while maintaining full UVLO2 functionality and thermal safety limits.
Does UCC5350SBD support negative voltage on its input pins?
Yes, UCC5350SBD allows –5 V on IN+ and IN– relative to GND1, enabling robust interface with legacy controllers or fault-signaling circuits that assert negative logic levels. This capability is explicitly specified in Absolute Maximum Ratings and does not require external clamping diodes.
How is UVLO2 implemented on UCC5350SBD, and why does it matter?
UVLO2 on UCC5350SBD is referenced to VEE2 - not GND2 - ensuring accurate detection of output-rail collapse regardless of VEE2 potential. This design prevents premature gate-disable during transient negative excursions and is critical for reliable operation in bipolar gate-drive topologies used with SiC and GaN FETs.
What isolation certifications apply to UCC5350SBD?
UCC5350SBD carries VDE certification per DIN V VDE V 0884-11:2017-01 (4242 VPK transient, 990 VPK repetitive), UL 1577 recognition (3000 VRMS for 1 minute), and CQC certification per GB 4943.1-2011 - all verified for the D-package variant.
Can UCC5350SBD replace optocoupler-based gate drivers in existing designs?
Yes, UCC5350SBD offers lower propagation delay (60 ns vs. >200 ns), higher CMTI (≥100 kV/µs vs. ~25 kV/µs), wider temperature range (–40°C to +125°C), and longer lifetime (>40 years barrier life) than typical optocouplers - but requires PCB layout updates to accommodate its SOIC-8 footprint and isolation barrier routing.
