EiceDriver X3 families eliminates external booster components
Two EiceDriver X3 gate drivers families launched by Infineon Technologies are claimed to accelerate design cycles, due to a lower external component count. The EiceDriver X3 Enhanced 1ED34xx devices are analogue gate driver ICs and the EiceDriver X3 Enhnaced1ED38xx are digital gate driver ICs.
The drivers provide a typical output current of 3.0, 6.0 and 9.0A, precise short-circuit detection, a Miller clamp and soft turn-off. In addition, 1ED34xx offers an adjustable desaturation filter time and soft turn-off current with external resistors. The 1ED38xx provides I2C configurability for multiple parameters, adds Infineon. This increases design flexibility, reduces hardware complexity and shortens evaluation time.
Both families of gate drivers are suitable for industrial drives, solar systems, uninterruptible power supplies, EV chargers and other industrial applications.
The EiceDRIVER X3 Enhanced 1ED34xx and 1ED38xx families are designed for IGBTs,SiC and Si MOSFETs in discrete and module packages. The output current of up to 9.0A eliminates the need for external booster components. Common mode transient immunity (CMTI) robustness is more than 200kV per microsecond, thus avoiding faulty switching patterns, reports Infineon. Both gate driver families feature a 40V absolute maximum output supply voltage and a tight propagation delay matching of 30 nanoseconds (max), resulting in shorter dead time. The I2C configurability options for the 1ED38xx include short circuit detection, soft turn off, under-voltage lockout (UVLO), a Miller clamp and over-temperature shutdown. The 1ED38xx gate driver family also offers a two-level turn-off through software settings.
The 1ED34xx and 1ED38xx gate drivers are provided in a small DSO-16 fine pitch package with 8.0mm creepage. Both are UL 1577-certified for 5.7kV RMS which, combined with precise thresholds and timings, ensures superior application safety, says Infineon. The gate driver ICs are built to withstand the rugged environments of industrial applications.
The EiceDRIVER Enhanced 1ED34xx and 1ED38xx are available to order now. Infineon also offers the EVAL-1ED3491MX12M evaluation board.
