Infineon Technologies has unveiled a new range of isolated gate drivers designed for hybrid IGBT and SiC inverter modules in electric vehicles (EVs).
The EiceDRIVER series is specifically optimized for Infineon’s latest HybridPACK Drive G2 Fusion module, the first plug-and-play power module to integrate both silicon and silicon carbide (SiC) technologies. This innovation simplifies the design process for EV powertrains.
The third-generation EiceDRIVER ICs—1EDI302xAS (for IGBTs) and 1EDI303xAS (for SiC Fusion)—are pre-configured, AEC-qualified, and ISO 26262-compliant, making them ideal for traction inverters in efficient and cost-effective electric vehicle platforms.
One standout feature of these gate drivers is their new tunable soft-off capability, which enhances short-circuit performance and ensures compatibility with the latest IGBT and SiC technologies.
Key Features and Applications
- High-Power Output:
The 1EDI3025AS, 1EDI3026AS, and 1EDI3035AS models deliver a robust 20 A output stage, packaged in a compact PG-DSO-20 format. These drivers are suitable for powering high-performance inverters across all power levels, exceeding 300 kW. - Entry-Level EV Solutions:
For lower-power applications, the 1EDI3028AS and 1EDI3038AS variants provide a 15 A output stage, making them ideal for entry-level battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and externally excited synchronous machines (EESMs). - Advanced Safety and Monitoring:
These gate drivers feature integrated monitoring functions, including a built-in self-test for desaturation protection (DESAT) and overcurrent protection (OCP), ensuring greater reliability by detecting latent system errors. A primary and secondary safe-state interface enhances system safety flexibility, while a continuously sampling 12-bit delta-sigma ADC with an integrated current source enables direct voltage readings from temperature diodes or NTCs. - Reinforced Insulation:
The drivers comply with the VDE 0884-17:2021-10 standard, offering reinforced insulation for safe operation and adhering to rigorous qualification and production testing processes.
