Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Littelfuse, noting previous branding under IXYS. Ensure the part number matches the exact pinout and electrical specifications required for the target circuit design before procurement.

Selection Notes

Select this component for applications requiring dual low-side isolation with high current drive. Consider the 40 ns propagation delay for timing-sensitive designs. Verify compatibility with the load type, specifically IGBTs and MOSFETs, and ensure the operating voltage remains within the 4.5 V to 35 V window.

Part Context

This device belongs to the IXDI series of high-speed gate drivers from Littelfuse. It serves as a specialized integrated circuit for power electronics, distinct from general-purpose logic drivers. The series is engineered for efficiency and speed in converting control signals into powerful gate drive pulses for power semiconductors.

Replacement Considerations

Check for direct substitutes within the IXDI family that share identical pinouts and electrical characteristics. Verify functional equivalence regarding drive current and delay times before substituting with other manufacturers' dual low-side drivers.
