Versatile short-circuit protection for power electronics systems

Infineon Technologies AG expands its portfolio of isolated EiceDRIVER Enhanced gate drivers with the F3 Enhanced (1ED332x) family. The gate driver family provides reliable and versatile protection to stop destructive short-circuit events. This enables conventional power switches, such as IGBTs, and CoolSIC wide-bandgap devices to be protected. The driver family is developed for industrial drives, solar systems, EV charging, energy storage systems, commercial air conditioning and other applications.

The device is housed in a 300mil wide-body DSO 16 package with a significant creepage distance of 8mm. The single-channel isolated gate driver delivers an exceptional high CMTI of up to 300kV/us and typical output currents of up to 8.5A. The tight propagation delay matching enables minimum deadtime enhancing system efficiency and decreasing harmonic distortion. The driver family offers short-circuit clamping and active shutdown, and an active Miller clamp.

The devices are created for wide power ranges and support 40V absolute maximum output voltage. Also, the driver family is ideal for operation at high ambient temperatures and in fast switching applications, making it excellent for rugged environments. As a result, it is ideal for conventional IGBTs, IGBT7 and SiC MOSFETs. Furthermore, its 2300V capability supports power switches beyond 1200V blocking voltage. UL 1577 and VDE 0884-11 (reinforced isolation) certifications ensure high application reliability and long service life.
