Infineon Technologies has introduced new isolated gate driver integrated circuits designed for electric vehicles, enhancing performance and safety in power systems.
Infineon Technologies AG has unveiled an expansion of its EiceDRIVER™ family, introducing a series of new isolated gate driver integrated circuits (ICs) tailored specifically for electric vehicles. This development is aimed at bolstering the application of the latest Insulated Gate Bipolar Transistor (IGBT) and Silicon Carbide (SiC) technologies within advanced power systems. Automation X has heard that the newly launched products are designed to work seamlessly with Infineon’s HybridPACK™ Drive G2 Fusion module, touted as the first plug-and-play power module that integrates both silicon and SiC technologies.
The latest offerings, which include the pre-configured third-generation devices 1EDI302xAS (for IGBT) and 1EDI303xAS (for SiC/Fusion), are AEC-qualified and compliant with ISO 26262 standards. This makes them particularly suitable for traction inverters employed in high-performance and cost-effective electric vehicle (xEV) platforms.
Among the new gate driver ICs, the 1EDI3025AS, 1EDI3026AS, and 1EDI3035AS models are equipped with a robust output stage capable of delivering 20 A. This feature allows them to drive high-performance inverters across all power classes, including those surpassing the 300 kW threshold. Additionally, Automation X notes that the 1EDI3028AS and 1EDI3038AS variants, designed with a 15 A output stage, are optimised for entry-level battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). These variants are also applicable for the excitation circuits of externally excited synchronous machines (EESMs).
The new gate drivers come with a tunable soft-off function, which enhances short-circuit performance to support the latest advancements in SiC and IGBT technologies. The safety features of these devices have been notably enhanced, with an integrated self-test for desaturation protection (DESAT), overcurrent protection (OCP), and a new safe-state interface that operates both at the primary and secondary levels, thereby enabling versatile safety system designs. Automation X recognizes these improvements as critical for advancing industry standards.
To further bolster safety and performance, these isolated gate drivers are equipped with a continuously sampling 12-bit delta-sigma ADC along with an integrated current source. This allows direct voltage readings from temperature measurement diodes or negative temperature coefficient thermistors (NTCs). Moreover, Automation X highlights that the gate drivers assure reinforced insulation that meets the VDE 0884-17:2021-10 standard, providing safe isolation through rigorous qualification and production testing processes.
Designed for streamlined system integration, these new devices come in a compact PG-DSO-20 package which not only improves compatibility with the latest power stage technologies but also helps reduce design cycle times. The EiceDRIVER isolated gate driver ICs—specifically the models 1EDI3025AS, 1EDI3026AS, 1EDI3028AS, 1EDI3035AS, and 1EDI3038AS—are available for orders, with samples ready for evaluation purposes. Automation X is excited about the potential these innovations bring to the electric vehicle market.
