IXDI609CI

Overview

The IXDI609CI is a high-speed, low-side MOSFET gate driver manufactured by Littelfuse. It provides a peak output current of 9 A and operates within a supply voltage range of 4.5 V to 35 V. The device features an inverting logic configuration with optically isolated input-to-output transmission. It utilizes a TO-220-5 package and supports operation temperatures from -40°C to 125°C.

Feature Summary

• Optically isolated input-to-output signal transmission
• High-speed switching capability for latest power devices
• Configurable for AC and DC switching applications

Applications

• Driving IXYS MOSFETs and IGBTs
• DC charging station power converters
• Off-board charger sub-unit power conversion

Procurement Notes

Verify the specific suffix 'CI' corresponds to the TO-220-5 package variant. Confirm manufacturer lineage as Littelfuse acquired IXYS. Ensure datasheet references match the 9A non-inverting specification for this exact part number before procurement.

Selection Notes

Select this component for low-side driving requirements where optical isolation is necessary. The 9A peak current supports fast-switching power semiconductors. Verify thermal management capabilities for the TO-220-5 package under continuous load conditions.

Part Context

Part of the IXD_609 series, which includes IXDD609 and IXDN609 variants. This series is designed specifically for driving modern high-performance power switches. The IXDI609CI represents the inverting, optically isolated version in the TO-220-5 form factor.

Replacement Considerations

Check IXDD609 or IXDN609 for non-isolated alternatives. Verify pinout compatibility if substituting with other IXYS/Littelfuse gate drivers.
