IXDI409YI

Overview

The IXDI409YI is a single-channel low-side gate driver IC manufactured by IXYS, designed for driving IGBTs and MOSFETs. It operates within a supply voltage range of 4.5V to 35V and delivers peak output currents of 9A for both sourcing and sinking. The device features ultrafast switching capabilities with typical rise and fall times of 10ns. It accepts inverting logic inputs compatible with CMOS and TTL standards, defined by VIL of 0.8V and VIH of 3.5V. The component is housed in a TO-263-5 surface-mount package and supports junction temperatures from -55°C to 150°C.

Feature Summary

• Ultrafast switching performance with 10ns rise and fall times for high-frequency applications
• High current drive capability providing 9A peak source and sink currents
• Wide operating supply voltage range supporting 4.5V to 35V operation
• Robust thermal design enabling operation up to 150°C junction temperature

Applications

• IGBT gate driving in industrial motor drives
• MOSFET control in high-efficiency power supplies
• Inverter circuits in renewable energy systems

Procurement Notes

Verify the specific suffix 'YI' corresponds to the TO-263-5 package variant. Confirm end-of-life status as the part is listed as obsolete. Ensure compatibility with existing PCB footprints before procurement. Check for authorized distributors offering remaining stock or qualified alternatives.

Selection Notes

Select this component when high-speed switching and robust current drive are required for low-side configurations. The inverting input logic must align with the control signal polarity. Consider the TO-263-5 package for thermal management needs. Verify that the 35V maximum supply voltage meets the isolated gate drive requirements of the target power devices.

Part Context

The IXDI409YI belongs to the IXDI409 family of ultrafast gate drivers. It shares functional similarities with the IXDI409SIA but differs in packaging, utilizing a D2PAK-style leaded package instead of SOIC. This series is engineered for demanding power electronics applications requiring fast transient response and high reliability under varying thermal conditions.

Replacement Considerations

The IXDI609SIA is documented as a similar replacement option. Verify pinout compatibility and electrical parameter alignment before substitution.
