The highest possible system efficiency is a key requirement for modern power electronics, which is driving the development of increasingly higher power densities. However, high-system values are at stake should short-circuit events occur.
The gate-driver family implements reliable and versatile protection to prevent destructive short-circuit events. This allows conventional power switches, such as IGBTs, as well as CoolSIC wide-bandgap devices to be protected.
The EiceDRIVER F3 Enhanced is housed in a 300 mil wide-body DSO 16 package with a large creepage distance of 8 mm. The single-channel isolated gate driver offers an exceptionally high, common-mode transient immunity (CMTI) — up to 300 kV/us and typical output currents of up to 8.5 A.
The tight propagation delay matching allows minimum deadtime improving system efficiency and decreasing harmonic distortion. 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 40 V absolute maximum-output voltage. In addition, the driver family is suitable for operation at high ambient temperatures and in fast switching applications, making it ideal for rugged environments.
As a result, it is ideally suited for conventional IGBTs, IGBT7 and silicon carbide (SiC) MOSFETs. Moreover, with its 2300 V capability, it supports power switches beyond 1200 V blocking voltage. UL 1577 and VDE 0884-11 (reinforced isolation) certifications ensure high-application reliability and guarantee a long service life.
