To expand its EiceDRIVER family, Infineon Technologies presents new isolated gate driver ICs for electric vehicles. The devices are said to be made to work with the newest SiC and IGBT technology.
Additionally, they are compatible with Infineon’s recently released HybridPACK Drive G2 Fusion module, which is the first plug-and-play power module to combine Infineon’s silicon and silicon carbide (SiC) technology.
AEC-qualified and ISO 26262-compliant, the pre-configured third-generation EiceDRIVER solutions, 1EDI302xAS (IGBT) and 1EDI303xAS (SiC/Fusion), are perfect for traction inverters in affordable and high-performing xEV platforms.
The 1EDI3025AS, 1EDI3026AS, and 1EDI3035AS devices operate high-performance inverters of all power classes up to more than 300 kW and offer a robust output stage of 20 A.
With a 15 A output stage, the 1EDI3028AS and 1EDI3038AS variations are perfect for usage in externally excited synchronous machines (EESM) excitation circuits and entry-level battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV) inverters.
To accommodate the newest SiC and IGBT technologies, the devices now have a new tunable soft-off function that offers superior short-circuit performance.
While the new primary and secondary safe-state interface allows for flexible system safety concepts, a number of monitoring features, including an integrated self-test for desaturation protection (DESAT) and overcurrent protection (OCP), enhance the handling of latent system problems.
Furthermore, a 12-bit delta-sigma ADC with an integrated current source that continually samples can read voltage straight from an NTC or temperature measurement diodes.
In accordance with VDE 0884-17:2021-10, the gate drivers also offer enhanced insulation to facilitate safe isolation in accordance with established qualification and production testing protocols.
Additionally, users may accelerate system integration and shorten design cycle times thanks to the PG-DSO-20’s small packaging and outstanding compatibility with the newest power stage technologies.
