Infineon Technologies AG introduced the EiceDRIVER™ 1ED301xMC12I family, a series of high-performance isolated gate driver ICs featuring an opto-emulator input. The devices are pin-compatible with existing opto-emulators and optocouplers and are designed to deliver higher common-mode transient immunity (CMTI), a robust output stage, and more accurate timing than typical opto-based solutions. This allows engineers to migrate to SiC technology while keeping established opto-based control schemes and avoiding a redesign.
The 1ED301xMC12I portfolio includes three variants—1ED3010, 1ED3011 and 1ED3012—covering Si MOSFET, IGBT and SiC MOSFET use cases. Each device provides up to 6.5 A output current, supporting power modules and parallel switch configurations. The ICs are offered in a CTI 600 6-pin DSO package with more than 8 mm creepage and clearance. Insulation is certified to UL 1577 and is pending certification to IEC 60747-17.
For switching precision and robustness, the opto-emulator interface uses a two-pin input designed for high noise immunity. The family specifies CMTI greater than 300 kV/µs, a propagation delay of 40 ns, and timing matching below 10 ns to support consistent high-speed switching behavior. A pure PMOS sourcing stage is included to improve turn-on performance.
The 1ED3010MC12I, 1ED3011MC12I and 1ED3012MC12I are available now through Infineon and its distribution partners. Infineon also offers the EVAL-1ED3012MC12I-SIC evaluation board to simplify testing with Infineon switches.
