Product details
Overview
UCC5390ECD from Texas Instruments is a single-channel isolated gate driver with UVLO referenced to GND2, 17A source/sink peak current, 60ns typical propagation delay, 100kV/µs CMTI, and SOIC-8 (D) package with 4mm creepage. It drives IGBTs, SiC MOSFETs, and GaN FETs in high-voltage motor drives and solar inverters.
For engineers reviewing the UCC5390ECD datasheet, UCC5390ECD pinout, UCC5390ECD application, or UCC5390ECD equivalent, this page delivers verified specifications, functional pin mapping, safety-certified isolation parameters, and direct alternatives for industrial power module design.
Technical Context
The UCC5390ECD implements galvanic isolation via capacitive barrier with CMOS input logic and output-side UVLO referenced to GND2-enabling true emitter-referenced undervoltage detection for IGBTs. Its architecture supports bipolar VEE2 supply (–16V to 0V) and up to 33V VCC2, enabling robust gate control under high dV/dt transients.
It features active pulldown on OUT, negative 5V input tolerance, and integrated short-circuit clamping (1.5V low-side clamp voltage). The device meets reinforced insulation requirements per DIN V VDE V 0884-11:2017-01 and UL 1577 at 3000VRMS for the D package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation rating | 3000VRMS (1 min), 4242VPK transient - certified per UL 1577 and VDE 0884-11 for basic insulation in industrial systems |
| Peak output current | 17A source & sink - enables fast switching of high-Qg SiC/GaN devices without external buffers |
| Propagation delay | 65–100ns (typ 65ns) - ensures tight timing control in high-frequency (>100kHz) power converters |
| CMTI | ≥100kV/µs - suppresses false triggering in noisy high-dV/dt environments like motor drives and EV inverters |
| UVLO2 reference | Referenced to GND2 - provides accurate gate-drive enable/disable relative to IGBT emitter potential |
| Operating temperature | –40°C to +125°C - supports under-hood and industrial ambient conditions without derating |
| VCC2 range | 13.2V to 33V - accommodates wide gate-drive supply rails for 15V/18V SiC and 20V+ GaN applications |
Pinout & Package
UCC5390ECD uses an 8-pin SOIC (D) package with 4mm creepage and clearance, rated for 3000VRMS isolation. Pin numbering follows standard SOIC-8 top-view layout (pin 1 = VCC1, pin 8 = VEE2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC1 | Input-side supply | 3–15V logic-side power; decoupling required near pin for noise immunity |
| IN+ | Noninverting input | CMOS threshold (0.55×VCC1); pulled low internally if floating - enables direct MCU interface |
| IN± | Inverting input | CMOS threshold (0.3×VCC1); pulled high internally if floating - supports differential or single-ended drive |
| GND1 | Input ground | Reference for all input signals and VCC1; must be separated from power ground |
| VCC2 | Output-side positive rail | 13.2–33V gate-drive supply; connects to high-side gate driver rail |
| GND2 | Emitter reference | Connects to IGBT emitter or MOSFET source; UVLO2 and OUT referenced here |
| OUT | Single-ended gate output | Drives gate directly; supports 17A peak; includes active pulldown and short-circuit clamp |
| VEE2 | Output-side negative rail | Bipolar supply pin: –16V to 0V relative to GND2 - enables negative turn-off bias for IGBTs |
Key Features
| Feature | Design Value |
|---|---|
| UVLO2 referenced to GND2 | Ensures reliable gate disable when IGBT emitter voltage rises during shoot-through or fault conditions |
| 17A peak source/sink current | Reduces external gate resistor dependency and enables <25ns rise/fall times into 1nF loads |
| 100kV/µs CMTI | Prevents false turn-on in >10kV/µs EMI environments common in SiC-based traction inverters |
| –16V to 0V VEE2 capability | Supports negative gate bias for enhanced IGBT short-circuit ruggedness and dv/dt immunity |
| SOIC-8 D package (4mm creepage) | Enables compact PCB layout while meeting IEC 61800-5-1 and UL 61800-5-1 reinforced insulation spacing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar isolated gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC5390SCD | Split-output (OUTH/OUTL) vs. single-output (OUT); identical 17A drive strength and D-package isolation | Requires separate gate resistors for turn-on/turn-off control; better for asymmetric rise/fall tuning in SiC designs | Select UCC5390SCD when independent control of gate rise/fall dynamics is needed; UCC5390ECD preferred for simplified layout and IGBT emitter-referenced protection. |
| Si8273ABD-IS | Lower 10A peak current; 5kVrms isolation (DWV-equivalent); no VEE2 support - only unipolar output | Lacks GND2-referenced UVLO and negative bias capability; unsuitable for IGBT short-circuit protection | Choose Si8273ABD-IS only for cost-sensitive, lower-power MOSFET applications where bipolar gate control is unnecessary. |
Compared with UCC5390SCD and Si8273ABD-IS, the UCC5390ECD uniquely combines emitter-referenced UVLO, bipolar VEE2 operation, and 17A drive in a 4mm-creepage SOIC-8 - making it optimal for IGBT-based industrial inverters requiring robust fault management without layout complexity.

FAQ
What is the isolation voltage rating of the UCC5390ECD?
The UCC5390ECD has a UL 1577-rated isolation voltage of 3000VRMS for 1 minute and a VDE-rated transient overvoltage of 4242VPK. These values apply to the SOIC-8 D package and are certified per DIN V VDE V 0884-11:2017-01 and UL 1577. The UCC5390ECD does not support the higher 5000VRMS DWV package variant.
Does the UCC5390ECD support negative gate voltage bias?
Yes, the UCC5390ECD supports negative gate bias via its VEE2 pin, which accepts –16V to 0V relative to GND2. This enables active negative turn-off for IGBTs and improves short-circuit ruggedness. The UCC5390ECD requires connection of VEE2 to a negative supply or GND2 depending on application needs.
How does UVLO2 referencing to GND2 benefit IGBT applications?
UVLO2 referencing to GND2 ensures the undervoltage lockout triggers relative to the IGBT emitter potential - not the driver's internal ground. This prevents premature disable during high-side switching transients and guarantees gate drive remains active until emitter voltage collapses during fault conditions. This behavior is intrinsic to the UCC5390ECD design.
What is the maximum recommended operating frequency for UCC5390ECD-driven switches?
The UCC5390ECD supports gate drive for switches operating up to 500kHz, based on its 10–22ns typical fall time (with 1nF load) and 65–100ns propagation delay. Real-world usable frequency depends on external gate resistance, switch Qg, and layout parasitics - but the UCC5390ECD itself imposes no hard upper limit below 1MHz.
Can the UCC5390ECD drive GaN HEMTs effectively?
Yes, the UCC5390ECD is qualified for GaN FETs per TI documentation. Its 17A peak current, <25ns switching times into 1nF, and 100kV/µs CMTI make it suitable for enhancement-mode GaN devices requiring fast, robust gate control. The UCC5390ECD's VEE2 pin also supports negative bias to prevent accidental turn-on in cascode configurations.
