Texas Instruments released two new gate drivers targeting IGBT and SiC FET designs. The UCC27531 and UCC27532 output stage gate drivers are, according to TI, the industry's first 35-V, single-channel, output stage power management gate drivers for insulated-gate bipolar transistors (IGBTs) and silicon carbide (SiC) field-effect transistors (FETs).
In a press release, TI says the designers are using SiC FETs and IGBTs in renewable energy applications to achieve lower power loss at greater than 400 V. "The UCC27531 and UCC27532 prevent the digital controllers from operating too close to the power circuitry, extending the lifetime of isolated power designs."
Features of the UCC27531:
Output drive capability: Peak current of 2.5 A source and 5 A sink allows fast charging of IGBTs and ensures reliable and efficient operation.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
