Infineon Technologies EiceDRIVER™ X3 1ED31xx family

The EiceDRIVER™ X3 Compact (1ED31xx) family is the next generation easy-to-design-in single-channel, isolated gate driver family with active Miller clamp or separate outputs.

The gate driver family provides typical peak output currents of up to 14 A, excellent propagation delays, and matching. This makes it ideal for conventional IGBTs, MOSFETs or SiC MOSFETs, and IGBT7. The active Miller clamp function is highly recommended for SiC MOSFETs and IGBT7 at 0 V turn-off. This avoids parasitic turn-ons and improves application safety. 

Key features

• For IGBTs (incl. IGBT7), SiC and Si MOSFETs
• 14 A typical output current, 7 ns propagation delay matching
• 90 ns propagation delay with 30 ns input filter
• 40 V absolute maximum output supply voltage

Additional features

• Separate source and sink outputs or Miller clamp
• DSO-8 300 mil wide-body package with large creepage distance (> 8 mm)
• 8 V or 10.5 V undervoltage lockout (UVLO) protection with hysteresis
• Additional Benefits:
  • Integrated filters reduce the need for external filters
  • Tight IC-to-IC turn on propagation delay matching (7 ns max.) improves application robustness & improves system efficiency
  • Suitable for operation in fast switching applications
  • UL 1577 (planned) VISO = 6.8 kV (RMS) for 1 s, 5.7 kV (RMS) for 1 min
  • The precise threshold and timings, combined with UL 1577 certification enable superior application safety

Applications

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

Available tools

• EVAL-1ED3122MX12H
  • This eval board is in a half-bridge configuration with two gate driver ICs (1ED3122MU12H) to drive power switches such as IGBTs and SiC MOSFETs. This board comes with TRENCHSTOP™ IGBT IKQ75N120CH3. An additional gate driver IC is used for isolated over-current feedback signals from the high voltage side to the logic control side. The fast operational amplifier is used as a comparator for over-current detection. This board is best suited for double-pulse testing.
