ISO5851 - High-CMTI 2.5-A and 5-A Isolated IGBT MOSFET Gate Driver

General Description

The ISO5851 is a 5.7-kVRMS, reinforced isolated gate driver for IGBTs and MOSFETs with 2.5-A source and 5-A sink current.

The input side operates from a single 3-V to 5.5-V supply.

The output side allows for a supply range from minimum 15 V to maximum 30 V.
