Infineon launches its first isolated gate driver ICs with opto-emulator input
Infineon introduces the EiceDRIVER 1ED301xMC12I product family, a series of high-performance isolated gate driver ICs with opto-emulator input. The devices are pin-compatible with existing opto-emulators and optocouplers, offering high common-mode transient immunity (CMTI), a robust output stage, and more precise timing than currently available solutions. This enables engineers to migrate to SiC technology without redesigning opto-based control schemes. The family is ideal for demanding applications where fast, reliable, and SiC-capable gate drivers are required, such as motor drives, solar inverters, electric-vehicle chargers, and energy-storage systems.
The 1ED301xMC12I product family includes three variants designed to support Si MOSFETs, IGBTs, and SiC MOSFETs: 1ED3010, 1ED3011, and 1ED3012. All devices deliver up to 6.5 A of output current, making them best-in-class for driving power modules and parallel switch configurations. The gate drivers come in a CTI 600 6-pin DSO package offering more than 8 mm creepage and clearance. Their insulation is certified according to UL 1577 and is pending certification according to IEC 60747-17. The opto-emulator input uses two pins and provides high robustness to noise. With a CMTI exceeding 300 kV/µs, a propagation delay of 40 ns, and timing matching below 10 ns, the devices enable precise and robust switching behaviour. Moreover, a pure PMOS sourcing stage further improves turn-on performance.
The isolated EiceDRIVER ICs 1ED3010MC12I, 1ED3011MC12I, and 1ED3012MC12I are available now and can be purchased from Infineon and its distribution partners. An evaluation board, EVAL-1ED3012MC12I-SIC, is also available, enabling easy evaluation with Infineon switches.
