IXDN604SI

Overview

The Littelfuse IXDN604SI is a dual low-side gate driver IC housed in an 8-SOIC package. It provides 4 A source and sink drive current, supporting IGBTs and N-channel/P-channel MOSFETs. The device operates within a supply voltage range of 4.5 V to 35 V. Key timing parameters include a propagation delay of 40 ns, turn-on delay of 50 ns, rise time of 9 ns, and fall time of 8 ns. It functions across an extended temperature range from -40 °C to +125 °C and holds AEC-Q100 Grade 1 qualification.

Feature Summary

• AEC-Q100 Grade 1 qualified for automotive reliability standards
• High-speed switching with ultrafast rise and fall times
• Robust logic input withstands high dv/dt noise
• Wide operating voltage range supports various power supply configurations

Applications

• Driving IXYS MOSFETs and IGBTs in power conversion circuits
• Automotive power electronics requiring AEC-Q100 compliance
• Industrial motor control systems
• Inverter bridge topologies

Procurement Notes

Verify the specific suffix 'SI' indicates the 8-SOIC package variant. Confirm AEC-Q100 Grade 1 certification status if automotive application is required. Ensure the supplier provides original manufacturer documentation to validate the Littelfuse or IXYS Integrated Circuits origin. Check RoHS compliance records for environmental regulatory adherence.

Selection Notes

Select this component when dual low-side driving capability is required for high-current MOSFETs or IGBTs. The 4 A peak current ensures fast switching transitions. The wide supply voltage range allows flexibility in logic interface design. Consider the SOIC-8 footprint constraints and thermal dissipation requirements for the specific PCB layout.

Part Context

This part belongs to the IXD_604 series of dual high-speed gate drivers. The series includes variants like IXDD604, IXDF604, and IXDI604, which share similar functional architectures but may differ in pinout or specific electrical characteristics. The IXDN604SI specifically denotes the low-side configuration with the standard industrial/automotive grade packaging.

Replacement Considerations

Cross-reference with IXDD604SI or IXDI604SI for potential pin-compatible alternatives within the same family. Verify that substitute parts maintain the 4 A drive current and AEC-Q100 qualification if those specifications are critical to the design.
