1EDI3028ASXUMA1

Overview

The Infineon Technologies 1EDI3028ASXUMA1 is an automotive-grade, single-channel high-side gate driver from the EiceDRIVER family. It utilizes coreless transformer technology for galvanic isolation with a reinforced isolation voltage of 5700 Vrms and a common mode transient immunity of 150 kV/µs. The device provides a peak output current of 15 A and operates within a supply voltage range of 3 V to 5.5 V. It features maximum propagation delays of 90 ns for both rising and falling edges, with typical rise and fall times of 35 ns and 45 ns respectively. The component is qualified to AEC-Q100 standards and functions reliably across an operating temperature range of -40°C to +150°C.

Feature Summary

• Employs coreless transformer technology for robust galvanic isolation and enhanced system reliability.
• Features a powerful output stage capable of driving IGBT and SiC power devices with high peak currents.
• Includes integrated diagnostic capabilities and active short-circuit protection for fault management.

Applications

• Electric vehicle traction inverters
• On-board chargers (OBC)
• DC-DC converters in automotive systems

Procurement Notes

Verify the specific suffix XUMA1 indicates tape-and-reel packaging when sourcing. Confirm AEC-Q100 qualification status matches project requirements. Check moisture sensitivity level handling procedures during assembly. Ensure compatibility with existing PCB footprint PG-DSO-20-91. Validate that the reinforced isolation rating meets safety standards for the target application voltage.

Selection Notes

Select this component for applications requiring high dv/dt immunity and precise timing matching between channels. It is suitable for replacing optocoupler-based solutions where higher reliability and faster switching speeds are needed. Consider the 15 A output capability against the gate charge requirements of the target power switch. Evaluate the need for integrated diagnostics if fault signaling is critical to the control loop.

Part Context

This part belongs to the EiceDRIVER series of isolated gate drivers designed specifically for electric vehicle powertrains. The series leverages magnetic coupling to provide superior performance over traditional optical isolation. These drivers are optimized for driving silicon carbide (SiC) MOSFETs and insulated-gate bipolar transistors (IGBTs) in high-voltage environments.

Replacement Considerations

Direct substitutes include other variants within the 1EDI302xAS family, such as the 1EDI3025AS or 1EDI3026AS, which share similar pinouts and coreless transformer technology but may differ in specific electrical parameters or diagnostic features. Verify functional equivalence before substitution.
