Infineon Technologies AG has introduced new isolated gate driver ICs for electric vehicles to enhance its EiceDRIVER™ family, which have been designed for the latest IGBT and silicon carbide (SiC) technologies.  

In addition, the gate driver ICs support the new HybridPACK™ Drive G2 Fusion module from Infineon, the first plug’n’play power module that implements a combination of silicon and SiC technologies, also developed by Infineon. The pre-configured third-generation EiceDRIVER products, 1EDI302xAS (IGBT) and 1EDI303xAS (SiC/Fusion), are AEC-qualified and ISO 26262-compliant, making them ideal for traction inverters in cost-effective and high-performant xEV platforms.

The 1EDI3025AS, 1EDI3026AS and 1EDI3035AS gate driver ICs provide a strong output stage of 20 A and drive high-performance inverters of all power classes up to over 300 kW. The variants 1EDI3028AS and 1EDI3038AS with an output stage of 15 A are ideal for use in entry-level battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV) inverters as well as for the excitation circuit of externally excited synchronous machines (EESM). In addition, the devices are equipped with the new tunable soft-off feature, which provides excellent short-circuit performance to support the latest SiC and IGBT technologies.

Various monitoring functions, such as an integrated self-test for desaturation protection (DESAT) and overcurrent protection (OCP), improve the handling of latent system errors while the new primary and secondary safe-state interface enables versatile system safety concepts. In addition, a continuously sampling 12-bit delta-sigma ADC with integrated current source can read the voltage directly from temperature measurement diodes or an NTC. The gate drivers also provide reinforced insulation according to VDE 0884-17:2021-10 to enable safe isolation following standardized qualification and production testing procedures. Furthermore, the compact package (PG-DSO-20) and excellent compatibility with the latest power stage technologies help customers to drive system integration and reduce design cycle times.

The new EiceDRIVER isolated gate driver ICs for EVs (1EDI3025AS, 1EDI3026AS, 1EDI3028AS, 1EDI3035AS, 1EDI3038AS) can be ordered now and samples are available.
