1EDI3021ASXUMA1

Overview

The Infineon Technologies 1EDI3021ASXUMA1 is an automotive-grade, single-channel high-voltage gate driver from the EiceDRIVER™ family. It utilizes coreless transformer technology for galvanic isolation and is optimized for IGBT applications. The device features a PG-DSO-20 package with reinforced insulation rated at 1200 V. It operates within a supply voltage range of 3 V to 5.5 V and delivers a peak output current of 20 A for both sourcing and sinking. Key timing parameters include a propagation delay of 60 ns, a rise time of 55 ns, and a fall time of 45 ns. It supports an operating temperature range from -40°C to +150°C and holds AEC-Q100 qualification.

Feature Summary

• High-side topology with reinforced galvanic isolation using coreless transformer technology
• Automotive qualification compliant with AEC-Q100 standards
• Optimized output stage specifically designed for driving IGBTs
• Integrated active Miller clamp functionality

Applications

• Electric vehicle traction inverters
• On-board chargers (OBC)
• DC-DC converters in automotive systems
• Industrial motor drives requiring high reliability

Procurement Notes

Verify the specific suffix XUMA1 indicates tape-and-reel packaging when ordering. Confirm that the component meets the required AEC-Q100 grade for your specific automotive application. Ensure design compatibility with the 1200 V isolation rating and 20 A output capability. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component for high-side IGBT driving where robust isolation and fast switching are critical. The 20 A output current supports medium-power modules. The 60 ns propagation delay offers precise control. Consider the PG-DSO-20 package size for PCB layout constraints. Verify thermal management needs given the 150°C maximum junction temperature capability.

Part Context

This part belongs to the EiceDRIVER™ series of isolated gate drivers from Infineon. These drivers replace traditional optocouplers by using magnetic coupling for signal transmission. The series provides enhanced common-mode transient immunity and better delay matching compared to optical solutions. It is part of Infineon's portfolio targeting electric mobility and industrial power electronics.

Replacement Considerations

Direct substitutes within the same family include 1EDI3021AS without the reel suffix. Other variants like 1EDI3023AS or 1EDI3028AS offer different current ratings but share similar isolation technologies. Verify pinout and electrical specifications before substitution.
