UCC5390ECDR Visão geral
An isolated gate driver is a specialized driver IC that provides both galvanic isolation and high-current drive signals to the gate of a power semiconductor. It sits hierarchically between a low-voltage PWM controller (signal-level logic) and a high-voltage power switch (MOSFET/IGBT/SiC), combining the functions of an isolation barrier (replacing optocouplers or pulse transformers) and a high-peak-current gate driver. Without it, a logic-level MCU cannot safely or directly switch a high-current power FET that may switch hundreds of volts.
Key features include 10A peak source and 10A peak sink output current, 3 kVRMS basic isolation rating per UL 1577, common-mode transient immunity (CMTI) of 100 kV/us minimum, and an 8-pin SOIC (D) footprint with 0.7 mm creepage. The split output stage (separate OUTH and OUTL pins) allows independent turn-on and turn-off strength tuning, and the device supports bipolar supply operation up to +18/-13 V for IGBT and SiC applications. The 12V UVLO references GND, while the part also carries safety certifications including UL 1577 and VDE 0884-11.
The UCC5390 uses TI's integrated capacitive isolation barrier with on-chip modulation/demodulation, eliminating the current-driven optocoupler lifetime concerns of LED-based isolators. Its split output topology lets the designer add discrete source/sink resistors to optimize dV/dt and EMI, which is critical when driving SiC MOSFETs at >50 V/ns to keep switching losses low.
Typical applications include solar string inverters, industrial motor drives, telecom and server power supplies, and EV onboard chargers. The 3 kVRMS rating suits 400V/600V/650V DC-link systems; the bipolar supply capability is critical for SiC MOSFETs that need a negative gate-off voltage to avoid spurious turn-on from high dV/dt.
When designing with this part, treat creepage/clearance on the PCB as the primary safety constraint. Above 1.5 kVRMS the SOIC-8 needs at least 4 mm side-to-side trace spacing and the inner PCB layers must be routed away from the isolation barrier to meet IEC 62368-1 reinforced isolation reinforcement.

Aplicações típicas
UCC5390ECDR é adequado para 6 aplicaçãos: Solar String Inverter Half-Bridge, Industrial AC Motor Drive (IGBT Inverter), Electric Vehicle Onboard Charger, Telecom and Server 48V Intermediate Bus Converter, Battery Energy Storage / UPS Bidirectional Inverter, Welding and Plasma-Cutter Power Stage.
Solar String Inverter Half-Bridge
The UCC5390ECDR drives 600V/650V SiC MOSFET half-bridges in 10-50 kW solar string inverters where the 3 kVRMS basic isolation and 10A peak source/sink current handle Qg values to 80 nC at 30-50 kHz switching. The 100 kV/us CMTI rating prevents spurious turn-on from the 50 V/ns dV/dt of SiC, and bipolar +/-15 V supply eliminates negative-OFF problems. Place a 5 ohm source resistor between OUTH and the gate to soften turn-on dV/dt, and a 3 ohm sinking resistor from OUTL to manage turn-off losses.
Recomendado
Industrial AC Motor Drive (IGBT Inverter)
The UCC5390ECDR drives 600V/1200V IGBT modules in 5-100 kW industrial VFDs where 10A source/sink current easily switches 200-600 A class modules. The 12 V UVLO protects against insufficient gate voltage at low-line input voltage, and the 3 kVRMS isolation satisfies IEC 61800-5-1 basic isolation between the low-voltage DSP and the 690 V DC-link. Use bipolar +15/-8 V supply to ensure reliable IGBT turn-off, with the negative rail generated by a small isolated DC-DC converter such as SN6505ADBVR.
Recomendado
Electric Vehicle Onboard Charger
In 6.6 kW to 22 kW EV onboard chargers, the UCC5390ECDR drives the primary-side PFC SiC MOSFETs and LLC secondary-rectifier SiC MOSFETs. The 3 kVRMS isolation is more than sufficient for the 400V output of a traction-battery charger but is often combined with a 5 kVRMS reinforced part for the IT-isolation requirements of IEC 61851-1. With Qg of 100 nC the 10A/10A peaks deliver 10 ns rise/fall times even with 5 ohm external gate resistors, minimizing switching loss across the full charging cycle from 3.6 kW to 22 kW.
Recomendado
Telecom and Server 48V Intermediate Bus Converter
In 48 V input, 12 V intermediate bus converters for servers and 5G base stations, the UCC5390ECDR drives 80V/100V GaN FETs or 150V Si MOSFETs in LLC topologies. The 10A source/sink current combined with the SOIC-8 footprint saves PCB area compared to gate-driver ICs in larger SOIC-16 packages - critical in 1U 48V-to-12V converters at 50-100 A output where board density is the dominant design constraint. Bipolar supply is not required for low-voltage converters; the part runs easily from a unipolar +12 V single rail.
Recomendado
Battery Energy Storage / UPS Bidirectional Inverter
Bidirectional inverters at 50-250 kW for battery energy storage and uninterruptible power supplies use the UCC5390ECDR to drive both the grid-side and battery-side IGBT bridge. With 10A peak current the part can switch 800 A class IGBT modules at 10-20 kHz with adequate headroom; the 3 kVRMS isolation is sufficient between the battery stack (up to 800 V DC) and the AC grid interface. Galvanic isolation helps meet UL 9540A safety, but for ST-grade bidirectional converters requiring active short-circuit protection the UCC21750 or UCC21710 is recommended instead.
Recomendado
Welding and Plasma-Cutter Power Stage
Industrial welding and plasma-cutter stacks drive 1200V IGBT modules at 20-50 kHz with dc-bus voltages to 700 V, where the UCC5390ECDR's 10A/10A drive strengths withstand the dv/dt extremes of short-circuit transfer to the arc. The 3 kVRMS isolation is more than enough across the low-voltage analog front-end and the high-voltage stack in a hard-switched 50 kW arc. Bipolar +/-15 V supply to the UCC5390ECDR is generated by the system's existing insulated gate-driver power tree; no extra winding is needed when the design is shared with a neighboring drive stage.

Notas de projeto
Maintain a 4 mm minimum side-to-side PCB trace spacing between the input-side (pins 1-4) and output-side (pins 5-8) to satisfy the UCC5390ECDR's 3 kVRMS basic isolation rating per IEC 62368-1. Remove inner PCB ground/power planes beneath the SOIC-8 body to avoid partial discharge paths. The exposed high-voltage node above the part can be a heatsink tab or transformer secondary; never route a low-voltage trace under the IC. Estimated: at 4 mm spacing in FR-4 PCB of 0.8 mm thickness the creepage clearance supports 1.5 kVRMS basic; choosing 4-layer stack-up with dedicated clearance slots supports 3 kVRMS ratings above this part.
The UCC5390ECDR's SOIC-8 thermal pad area is small (theta-JA around 100 C/W on a 1 oz 2-layer PCB without extra copper). At sustained 100 kHz operation driving 80 nC gates, the gate-charge power dissipation reaches P = Qg * V * f = 80e-9 * 15 * 100e3 = 120 mW, well within the 0.6 W SOIC-8 envelope. For 4 A/4 A alternative parts like UCC23313, use a 4-layer board with a 0.5 square-inch copper ground plane under the IC. Estimated: at 100 kHz and 80 nC this is non-critical, but if switching frequency exceeds 300 kHz, validate by thermal camera measurement.
Do not operate the UCC5390ECDR without a bipolar supply bypass network. Place a 4.7 uF X7R ceramic plus 0.1 uF X7R ceramic directly across VDD2 (pin 5) and VEE2 (pin 6) within 5 mm of the package. The high peak source/sink currents (10 A) create di/dt transients of 1 A/ns, and missing bulk capacitance causes rail collapse and spurious MOSFET turn-on in half-bridge topologies. Estimated: with 1 inch un-gapped trace length every additional 0.1 nH of loop inductance adds 0.5 V to the rail-ripple amplitude at 1 A/ns, so the bypass network location matters more than its capacitance value.
Use split OUTH and OUTL pins with separate gate resistors to tune dV/dt independently: 5 ohm on OUTH softens turn-on to reduce ringing, while 1-2 ohm on OUTL provides fast turn-off to minimize switching losses. This split-output topology also reduces EMI from downstream L*di/dt loops. Estimated: a 5 ohm source resistor increases turn-on rise time to ~40 ns (vs ~10 ns without), reducing the inductive voltage spike from 5 V to 1.2 V across the parasitic 1 nH source inductance.
