Texas Instruments has introduced several new isolated gate drivers that provide unparalleled levels of monitoring and protection for high voltage systems. The UCC21710-Q1 and UCC21732-Q1 and UCC21750 enable designers to create smaller, more efficient and higher performing designs in traction inverters, onboard chargers, solar inverters and motor drives.
The devices offer integrated sensing features for Insulated-Gate Bipolar Transistors (IGBTs) and Silicon Carbide (SiC) Metal-Oxide Semiconductor Field-Effect Transistors (MOSFETs) to simplify designs and enable greater system reliability in applications operating up to 1.5KVRMS.
With integrated components, the devices provide fast detection time to protect against overcurrent events while ensuring safe system shutdown.
Utilising capacitive isolation technology, the UCC21710-Q1, UCC21732-Q1 and UCC21750 maximise insulation barrier lifetimes while providing high reinforced isolation ratings, fast data speeds and high density packaging.
“System robustness is becoming an increasing challenge in high voltage motor drive and power delivery applications,” said Steve Lambouses, Vice President, TI high voltage Power. “These new gate drivers using TI’s isolation technology, combined with the other integrated features and support, can enable engineers to more quickly ramp to production reliable systems, while minimising space and cost.”

Advanced system performance and reliability at any power level
For designers of industrial applications needing increased noise immunity and wider operating temperatures, TI also announces the UCC23513, an opto-compatible gate driver with 3A drive strength and 5KVRMS reinforced safety isolation.
Developed to maximise system performance and reliability in motor drives, solar inverters and power supplies, the new gate driver offers a wide junction temperature range from -40ºC to +150ºC and high CMTI greater than 100 V/ns - enabling designers to achieve levels of performance not available with traditional optocouplers.
Designers can accelerate time to market with the UCC23513’s pin-to-pin compatibility with opto isolated gate drivers and ready-to-use design resources, including the Three-phase inverter reference design for 200-480 VAC drives with opto-emulated input gate drivers.
