Post Date: 2021-06-30, Infineon Technologies

Infineon Technologies AG has expanded its easy-to-design EiceDRIVER X3 Compact (1ED31xx) and highly flexible EiceDRIVER X3 enhanced analog (1ED34xx) and digital (1ED38xx) gate driver series. These series now offer variants with excellent reinforced isolation to achieve higher application security and longer service life. Members of the new series have passed VDE 0884-11 certification. This series adopts 8mm wide body package, very suitable for applications with demanding isolation requirements, including industrial drives, UPS, solar systems, electric vehicle charging and other industrial applications.

This multifunctional series offers 5.5A, 10A and 14A drive currents and an optimized propagation delay of 90ns. This series also includes a Miller clamp, which is highly recommended for SiC MOSFET 0V turn-off. With these options, 1ED31xx is ideal for high switching frequency applications, IGBT7 and power switches with rated voltages up to 2300V.

This series provides accurate and adjustable DESAT, as well as further configurable parameters based on I2C. This supports a high degree of design flexibility and reduces hardware complexity and evaluation time. In addition, the built-in monitoring function facilitates predictive maintenance.
