IXDI614CI

Overview

The Littelfuse IXDI614CI is a high-speed, low-side gate driver designed for driving modern IXYS MOSFETs and IGBTs. It delivers a peak output current of 14A for both sourcing and sinking, ensuring rapid switching with voltage rise and fall times under 30ns. The internal circuitry eliminates cross-conduction and shoot-through issues, providing robust performance with minimal latch-up risk in power conversion applications.

Feature Summary

• High-speed operation with ultra-fast voltage transition times
• Capable of sourcing and sinking 14A peak output current
• Internal protection against cross-conduction and shoot-through currents
• Optimized compatibility with IXYS MOSFET and IGBT devices

Applications

• Driving IXYS MOSFETs in power supply circuits
• Driving IXYS IGBTs in industrial inverters
• High-frequency switching power converters
• Motor drive control systems

Procurement Notes

Verify the specific suffix (CI) to confirm commercial grade temperature range and package type. Ensure the supplier provides official Littelfuse or IXYS documentation. Confirm pinout alignment with DIP-8 or SOIC-8 footprints depending on the exact variant received. Check for AEC-Q100 qualification if automotive use is intended, as this may require the SI suffix.

Selection Notes

Select the IXDI614CI when high peak current capability is required for fast-switching power semiconductors. It is suitable for designs prioritizing reduced switching losses through sub-30ns transitions. Consider the low-side configuration constraint. Evaluate thermal management requirements based on the 14A peak current handling capability during switching events.

Part Context

This component belongs to the IXD_614 family of high-speed gate drivers from Littelfuse/IXYS. The family includes variants like IXDD614 and IXDN614, sharing core electrical characteristics but differing in packaging or specific optimization. The CI suffix typically denotes a commercial temperature range and standard plastic package.

Replacement Considerations

Direct substitutes within the same family include IXDD614 and IXDN614, provided package compatibility is verified. For automotive applications requiring AEC-Q100 qualification, consider the IXDI614SI variant. Cross-referencing with other 14A low-side drivers requires verifying peak current, propagation delay, and supply voltage ranges.
