Technical Highlights: Why the 1EDI3021 Is Ideal for Automotive Power Designs

Coreless transformer isolation combines safety with a compact design. This device utilizes Infineon’s Coreless Transformer technology to enable bidirectional signal transmission across the isolation barrier, achieving an enhanced isolation level within the PG-DSO-20 package. This helps reduce the number of system-level isolation components and PCB footprint. For space-constrained applications with stringent safety requirements, such as traction inverters, this feature directly simplifies the BOM.

150 V/ns CMTI for Suppressing Switching Noise Interference. During high-speed IGBT switching, common-mode transients caused by high dv/dt are the primary risk for gate driver false triggering. The 1EDI3021 achieves a typical CMTI of 150 V/ns, maintaining signal integrity in high-power-density designs and reducing noise-induced shoot-through or false shutdowns.

60 ns propagation delay, enhancing control loop response. For motor drives, the timing accuracy of drive signals directly affects current-loop bandwidth and torque response. A propagation delay in the 60 ns range enables the controller to apply dead-time compensation and protection actions with greater precision; particularly when used in conjunction with the ASC pin in PMSM motor drives, it allows for rapid triggering of safety states.

ASIL B(D) safety features and pre-configuration advantages. The device integrates advanced driver diagnostics and supports ISO 26262 ASIL B(D) system safety objectives. It can be put into service via pre-configured parameters without requiring SPI programming, thereby shortening the development and certification cycles for safety-critical projects.

Typical Applications

Electric Vehicle Main Traction Inverters. The 1EDI3021 is optimized for 1200 V IGBTs and is suitable for the gate drive requirements of high-power IGBT modules in main traction inverters. Its enhanced isolation and high CMTI capability address the high-voltage, high-noise environments found in motor controllers.

On-Board Chargers (OBC) and DC-DC Converters. In the PFC and DC-DC stages of OBCs, isolated gate drivers must provide reliable isolation within limited space. The device’s compact DSO-20 package and preconfigured features help reduce the volume of the OBC power stages.

Industrial motor drives and auxiliary inverters. In addition to automotive applications, this chip is also suitable for industrial drives, auxiliary inverters, and excitation circuits for externally excited synchronous motors—all of which require 1200 V IGBT isolation drivers.
