Qualified high-voltage MOSFET, IGBT, and SiC gate driver technology
The Infineon EiceDRIVER™ high-voltage gate driver family for xEV applications includes automotive IGBT driver ICs and SiC MOSFET, providing galvanic isolation, and bidirectional signal transmission with high ambient temperature capability. They enable extremely short propagation delays keeping the designer’s flexibilities at the highest level while providing galvanic isolation using the robust Infineon coreless transformer (CT) technology. They support IGBT and SiC technologies up to 1200 V. Advanced monitoring and protection features facilitate the implementation of ISO 26262 functional safety requirements.
SiC power electronics such as CoolSiC™ - when used in xEV applications such as the main inverter, onboard charger and DC-DC converter - increase the driving range of (hybrid) electric vehicles and reduce energy losses during charging. In the automotive EiceDRIVER™ portfolio, the 1EDI303xAS variants are optimized for SiC and the portfolio will be steadily extended.
EiceDRIVER™ family products are ideal for automotive applications, such as main inverters, DC-DC converters or onboard chargers, where efficiency, space savings and safety are priorities.
Gate driver ICs for automotive power distribution
Infineon's automotive gate driver ICs for automotive power distribution can address various applications from today's distributed, through central domain oriented to centralized zonal E/E architectures. EiceDRIVER™ APD together with Infineon automotive MOSFETs combines the function of a relay and a fuse, but with much better performance in terms of response time, shutdown accuracy, power consumption, and diagnostic capabilities. Gate driver ICs plus MOSFETs are typically used once higher load currents need to be switched, or more design flexibility is requested.
