Infineon Technologies EiceDRIVER™ X3 1ED34xx & 1ED38xx family

A highly flexible high-end single-channel, isolated gate driver family with DESAT, Miller clamp, Soft-off, and I²C configurability.

The X3 Analog (1ED34xx) & X3 Digital (1ED38xx) mark a highly flexible isolated gate driver family, offering a wide range of configurable features and monitoring options. This enables innovative use cases, such as predictive maintenance.

The gate driver family provides typical peak output currents of 3 A, 6 A, and 9 A, high precision DESAT function, an excellent solution for short-circuit protection for IGBTs and SiC MOSFETs; many of those features configurable.

Key features

• 40 V absolute maximum output supply voltage
• For IGBTs (incl. IGBT7), SiC and Si MOSFETs
• ±3/6/9 A typical sinking and sourcing peak output current
• Precise VCEsat detection (DESAT) with fault output

Additional features

• Flexibility based on feature configuration
  • Adjustable DESAT filter time and soft-off current level (1ED34XX)
  • I2C configurability for DESAT, soft-off, UVLO, active Miller clamp, over temperature shutdown, two level turn off (1ED38XX)
• UL 1577 (pending) VISO = 6 kV (rms) for 1 s, 5.7 kV (rms) for 1 min 

Applications

• Industrial motor drives
• Solar inverters
• UPS systems
• EV-charging
• Energy storage systems

Available tools

• EVAL-1ED3491MX12M:
  • This is an eval board in a half-bridge configuration with two gate driver ICs (1ED3491MU12M) to drive power switches such as Si MOSFETs, IGBTs, and SiC MOSFETs. The switch type can be freely chosen. The board has a size of 85 x 55 x 15 mm without any power switch assembled. TRENCHSTOP™ IGBT IKW40N120H3 or CoolSiC™ MOSFET IMW120R030M1H is recommended. This board is best suited for double pulse testing and evaluation. The low voltage supply interface can be controlled by a pulse generator, a microcontroller, or any other suitable digital circuit. The evaluation board has a power supply for the primary and secondary sides implemented.
