2EDR8258X

Überblick

Fast, robust, dual-channel, functional isolated MOSFET gate drivers with accurate and stable timing.

The EiceDRIVER™ 2EDR8258X is a reinforced isolated gate driver IC for control over the mandatory safe isolation barrier in SMPS. The strong 5 A/9 A source/sink dual-channel gate driver comes with a very high 150 V/ns CMTI (common mode transient immunity) for robust operation with CoolMOS™, CoolGaN™ GIT HEMTs and high-power switching noise environment.

The very short propagation delay of 38ns is provided with low variation over temperature and production which enables the power system design to achieve higher efficiency through very tight timing control across the safety isolation barrier. Safety certificates in accordance with UL1577, VDE0884-11, IEC 60747-17, IEC62368 and GB4943.1 are available. 2EDR8258X is available in a wide-body 300 mil DSO-14 package.
