High speed switching and high frequency operation performance.Reference design for PCB layout and gate driver circuit.Support continuous power supply test depending on thermal design (up to 400W / 800W using attached heatsink).Support evaluation of switching characteristics using 2-pulse test.High integration, low propagation delay, small installed size, flexibility, and cost-effectiveness make the Si827x family suited for a wide range of isolated MOSFET/IGBT and SiC or GaN FET gate drive applications.įeatures of the Panasonic GaN half-bridge evaluation boards include: The TTL level compatible inputs with >400 mV hysteresis are available in individual control input (Si/5) or pwm input (Si8274) configurations. The Si827x drivers utilize Silicon Labs' proprietary silicon isolation technology, which provides up to 2.5 kVRMS withstand voltage per UL1577 and fast 60ns propagation times.ĭriver outputs in the Si827x can be grounded to the same or separate grounds or connected to a positive or negative voltage. The Si827x series offers longer service life and dramatically higher reliability compared to opto-coupled gate drivers. It also offers unique features such as separate pull-up/down outputs, driver shutdown on UVLO fault, and precise dead time programmability. This technology enables industry leading common-mode transient immunity (CMTI), tight timing specifications, reduced variation with temperature and age, better part-to-part matching, and extremely high reliability. The Si827x isolated gate drivers utilize Silicon Laboratories' proprietary silicon isolation technology, supporting up to 2.5kVRMS withstand voltage per UL1577 and VDE0884. The Si827x isolators are designed for driving power switches used in a wide variety of power supply, inverter, and motor control applications. The AN34092B is a single-channel high-speed gate driver specialized to driving GaN power transistor (GaN-Tr). Key devices in these evaluation boards include: X-GaN 70mΩ - PGA26E07BA (600V / 26A) X-GaN 190mΩ - PGA26E19BA (600V / 13A) X-GaN driver - AN34092B and Isolator - Silicon Laboratories Si8275. The PGA26ExxBA-SWEVB008 is a half-bridge evaluation board for measuring the switching characteristics of the GaN power transistor and can be easily configured into any half-bridge topology for power supply evaluation. now offers the PGA26E07BA-SWEVB008 (800W) and PGA26E19BA-SWEVB008 (400W) half-bridge evaluation boards (with dedicated X-GaN driver + general isolator) for evaluating the performance of Panasonic's X-GaN power transistors.
