Infineon – EiceDRIVER™ Isolated Gate Driver IC

Compact

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 the application safety.

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
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

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

Evaluation Board: EVAL-1ED3122Mx12H

The EVAL-1ED3122MX12H is in 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 signal from high voltage side to logic control side. Fast operational amplifier is used as comparator for over-current detection. This board is best suited for double-pulse testing.

EVAL-1ED3122Mx12H Application Note

EVAL-1ED3122Mx12H Evaluation board includes:

TRENCHSTOP™ IGBT IKQ75N120CH3
Additional gate driver IC
Fast operational amplifier

Enhanced

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 shortcircuit protection for IGBTs and SiC MOSFETs – many of those features configurable. This flexibility makes it a unique high-end solution in the market.

Features

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
40 V absolute maximum output supply voltage
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)

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)
UL 1577 (pending) VISO = 6 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
