IXDI604SIATR

Overview

The Littelfuse IXDI604SIATR is a dual low-side gate driver IC designed for high-speed switching applications. It features two independent output channels capable of delivering a peak pulse current of 4 A, suitable for driving MOSFETs and IGBTs. The device operates within a supply voltage range of 4.5 V to 35 V. Key electrical characteristics include a propagation delay of 40 ns, an on-delay time of 50 ns, and rise/fall times of 9 ns and 8 ns, respectively. It supports automotive standards with AEC-Q100 qualification and functions reliably across a temperature range of -40 °C to 125 °C.

Feature Summary

• Dual-channel low-side configuration for independent control of power switches
• High-speed operation with ultrafast rise and fall times for efficient switching
• Automotive-grade reliability certified under AEC-Q100 standards
• Robust drive capability supporting both N-channel and P-channel MOSFETs as well as IGBTs

Applications

• Industrial motor drives and inverters
• Automotive power electronics and engine control units
• High-frequency DC-DC converters and power supplies

Procurement Notes

Verify the specific suffix 'A' indicates AEC-Q100 automotive qualification. Confirm the 'TR' suffix denotes tape-and-reel packaging rather than tube. Ensure the component matches the SOIC-8 package dimensions and pinout. Check RoHS compliance status against current regulatory requirements. Validate supplier authenticity through authorized Littelfuse distribution channels.

Selection Notes

Select this component when dual isolated low-side driving is required for automotive or industrial environments. Consider the 4 A peak current capability for moderate-power MOSFETs. Evaluate the 40 ns propagation delay against system timing constraints. Compare operating temperature limits with ambient conditions. Verify compatibility with logic-level input signals within the 4.5 V minimum supply requirement.

Part Context

This part belongs to the IXDI series of high-speed gate drivers from Littelfuse. It is specifically engineered for demanding power conversion applications where speed and reliability are critical. The series offers various channel configurations and drive strengths, with this model focusing on dual low-side performance in a compact surface-mount package.

Replacement Considerations

Direct substitutes may include other dual low-side drivers with similar 4 A output current and SOIC-8 packaging. Verify pin-to-pin compatibility and electrical specifications such as supply voltage range and propagation delay. Ensure any replacement also meets AEC-Q100 automotive qualification if required by the design.
