2EDN7434FXTMA1

Gate Driver Overview

The Infineon Technologies 2EDN7434FXTMA1 is a dual-channel low-side gate driver IC from the EiceDRIVER family, designed for industrial applications. It features a non-isolated topology with two independent outputs capable of sourcing and sinking 4 A each. The device operates within an input supply voltage range of 4.2 V to 20 V and supports switching devices including GaN SG HEMTs, IGBTs, and MOSFETs. Key electrical parameters include a maximum propagation delay of 25 ns, rise time of 8.6 ns, and fall time of 6 ns. It utilizes a PG-TSSOP-8 package and functions reliably across a temperature range of -40 °C to +150 °C.

Gate Driver Procurement Notes

Verify the specific suffix 'XTMA1' against the manufacturer's official datasheet to confirm packaging details and tape-and-reel specifications. Ensure compatibility with the target PCB footprint, specifically the PG-TSSOP-8 package dimensions. Cross-reference the RoHS compliance status with the latest product declaration documents provided by Infineon Technologies before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when a dual-channel low-side driver with 4 A output current is required for industrial-grade reliability. The non-isolated design suits applications where galvanic isolation is not mandated between the control logic and the power stage. Consider the 20 V maximum supply rating and the specific propagation delays when designing for high-speed switching requirements in compact power modules.

Gate Driver Part Context

This part belongs to the Infineon EiceDRIVER™ 2EDN series, which focuses on low-side gate driving solutions using advanced 0.13 µm CMOS technology. The series emphasizes high current density and robust protection features within small form factors like DSO-8 and TSSOP-8. These drivers are engineered to replace older discrete solutions, offering improved performance and reduced board space for modern power electronics designs.

Gate Driver Replacement Considerations

Consult the official Infineon replacement guide for the EiceDRIVER™ 2EDN series to identify direct pin-to-pin or functional substitutes. Verify that any alternative component matches the 4 A output current, 20 V supply range, and TSSOP-8 package constraints.
