400 V Half Bridge Converter Two Single Channel Galvanic Isolated Gate Driver IC
EiceDRIVER™ 1ED3121MU12H

Typical application circuit

The 1ED3121MU12H gate driver ICs are galvanically isolated single channel gate driver ICs for
IGBT, MOSFET and SiC MOSFET in PG-DSO-8 package. They provide a typical output current of up to 5.5 A on
separate source and sink pins or a typical output current of 5.5 A with an additional 3.0 A active Miller clamp.
The input logic pins operate on a wide input voltage range from 3 V to 15 V using CMOS threshold levels to
support 3.3 V microcontrollers.

Data transfer across the isolation barrier is realized by the coreless transformer technology.

All variants have logic input and driver output under voltage lockout (UVLO), and active shutdown.
The gate drivers are certified according to VDE 0884-11 and UL 1577
