Infineon Technologies EiceDRIVER™ X3

This release of X3 Analog (1ED34xx) & X3 Digital (1ED38xx) adds products with reinforced isolation according to VDE 0884-11 to the existing highly flexible, single-channel, isolated gate driver family with DESAT, Miller clamp, soft-off and I2C configurability.

The gate driver family provides typical peak output currents of 3 A, 6 A and 9 A, high precision DESAT function for IGBTs and SiC MOSFETs; many of those features configurable. This enables innovative use cases, such as predictive maintenance.

Key features

• Reinforced isolation according to VDE 0884-11
• 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

• 40 V absolute maximum output supply voltage
• Flexibility based on feature configuration

Additional Benefits

• Enables fast design cycles due to low external component count and still offers adjustable DESAT with soft-off functionality
• Perfect fit for all applications requiring a reliable DESAT protection (including SiC MOSFET & IGBT7),
• VDE 0884-11 with VIORM = 1767 V (peak, reinforced) and UL 1577 (pending) VISO = 6 kV (rms) for 1 s, 5.7 kV (rms) for 1 min
• Superior application safety based on VDE 0884-11 and UL 1577

Applications

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

EVAL-1ED3491MX12M

Evaluation board for 1ED3491Mx12M - 2300 V, 9 A, single-channel flexible isolated gate driver with active Miller clamp, adjustable DESAT and Soft-off

The EVAL-1ED3491MX12M is in 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. 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.
