Infineon adds F3 Enhanced EiceDriver for short-circuit protection
Protecting increasing power densities from short-circuit events, Infineon Technologies has added the F3 Enhanced (1ED332x) family to its isolated EiceDriver Enhanced gate drivers. According to Infineon, the gate driver family implements reliable and versatile protection to prevent destructive short-circuit events. This allows both conventional power switches, such as IGBTs, as well as CoolSIC wide-bandgap devices to be protected.
The driver family is designed for industrial drives, solar systems, electric vehicle charging, energy storage systems, commercial air conditioning and other applications.
The EiceDriver F3 Enhanced is housed in a 300-mil wide-body DSO-16 package with a large creepage distance of 8.0mm. The single-channel isolated gate driver offers a high common-mode transient immunity (CMTI) of up to 300kV per microsecond and typical output currents of up to 8.5A. The tight propagation delay matching allows minimum deadtime improving system efficiency and decreasing harmonic distortion, said the company. The driver family provides short-circuit clamping and active shutdown as well as an active Miller clamp.
The devices are designed for wide power ranges and support 40V absolute maximum output voltage. They are also suitable for operation at high ambient temperatures and in fast switching applications in rugged environments. Infineon advise can be used for conventional IGBTs, IGBT7 and SiC MOSFETs. The 2,300V capability allows the driver to support power switches beyond 1,200V blocking voltage. The drivers also have UL 1577 and VDE 0884-11 (reinforced isolation) certification for high application reliability and long service life.
The EiceDriver F3 Enhanced and the evaluation board EVAL-1ED3321MC12N (pictured) can be ordered now.
