IFX1EDB8275FXUMA1
Overview
The 1EDB8275FXUMA1 is a single-channel isolated gate driver from Infineon's EiceDRIVER family designed for high-performance power switching. It provides galvanic isolation with high common-mode transient immunity of over 300 V/ns, making it suitable for driving SiC and GaN MOSFETs in noisy environments. This specific variant features an 8V Under-Voltage Lockout (UVLO) threshold to ensure safe operation of power transistors.
Why Choose This Part
This driver delivers a peak output current of up to 9.8A with separate source and sink outputs for independent turn-on and turn-off optimization. It features exceptionally high CMTI (>300 V/ns) and fast startup times, ensuring robust performance during rapid load changes or supply glitches.
Applications
Getting Started
When designing with the 1EDB8275FXUMA1, ensure the VDDO supply is decoupled with low-ESR ceramic capacitors placed close to the DSO-8 package pins. Engineers should verify that the 8V UVLO threshold aligns with the Miller plateau and safe operating area of the chosen power MOSFET. Evaluation can be performed using Infineon's EiceDRIVER isolated gate driver evaluation boards.
