1EDC20I12MHXUMA1

Overview

The 1EDC20I12MHXUMA1 is a single-channel isolated gate driver IC from Infineon's EiceDRIVER™ family, designed for high-voltage power switching applications. It utilizes magnetic coupling technology to provide galvanic isolation with a rated voltage of 2500 Vrms. The device features separate output terminals for the drain and source connections, facilitating independent control and monitoring. It supports IGBT and MOSFET switching with peak output currents of 2 A source and 3.5 A sink. Key electrical parameters include a propagation delay of 165 ns (shutdown) and 170 ns (turn-on), with rise and fall times of 10 ns and 9 ns respectively. The operating supply voltage range spans from 3.1 V to 17 V, and it functions within a temperature range of -40°C to +150°C TJ.

Feature Summary

• Integrates magnetic coupling technology for robust galvanic isolation without optical components.
• Provides separate output terminals for independent drain and source connection management.
• Includes integrated active Miller clamp functionality to prevent unintended turn-on events.

Applications

• Driving IGBT modules in industrial motor drives
• Switching SiC MOSFETs in high-frequency power converters
