2EDB8259K - Infineon Technologies

综述

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

The EiceDRIVER™ 2EDB8259K is a dual channel isolated gate driver IC with floating outputs. 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 OptiMOS™ in 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. Safety certificates in accordance with UL1577 and GB4943.1 are available. 2EDB8259K is available in a 13-pin LGA 5x5 mm package.
