IXDI604SIA

Overview

The Littelfuse IXDI604SIA is a dual low-side gate driver designed for driving N-channel and P-channel MOSFETs as well as IGBTs. It operates within a supply voltage range of 4.5 V to 35 V and supports an extended operating temperature range from -40 °C to +125 °C. The device features two non-inverting outputs capable of delivering a peak pulse current of 4 A. Key timing specifications 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 is housed in an 8-pin SOIC surface-mount package.

Feature Summary

• Dual low-side configuration with independent channel control
• Ultrafast switching performance with nanosecond-level propagation delays
• Wide operating voltage range supporting various logic levels
• Extended temperature rating suitable for harsh environments

Applications

• Industrial motor drives
• Power supply inverters
• High-frequency switching circuits

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to ensure correct pinout and inversion logic. Confirm RoHS compliance status and packaging type (tube) matches project requirements. Check for lead-free certification if required by regulatory standards.

Selection Notes

Select this component when dual low-side driving is required for MOSFETs or IGBTs with high-speed switching needs. Ensure the load capacitance and required drive current are within the 4 A peak limit. Verify that the input signal polarity matches the inverting nature of the IXDI series compared to non-inverting alternatives.

Part Context

This part belongs to the IXD series of ultrafast gate drivers from Littelfuse. The series includes variants such as IXDD604 (non-inverting with enable), IXDN604 (non-inverting), and IXDF604. The IXDI604 specifically provides dual inverting outputs, distinguishing it from the non-inverting counterparts in terms of signal phase relationship.

Replacement Considerations

Direct substitutes include other IXDI604 variants from Littelfuse. Cross-referencing with IXDD604 or IXDN604 requires accounting for the difference between inverting and non-inverting output logic.
