About this document
Scope and purpose
This application note provides an overview of the evaluation board EVAL-M1-2ED2106S concerning its main
features, hardware description, thermal performance and typical waveforms, etc.
The EVAL-M1-2ED2106S board is a power drive board including driver ICs, IGBTs, a power connector and signal
interface. The board is intended to drive a brushless direct current (BLDC) motor by connecting to an external
controller board such as EVAL-M1-101T.
The board aims to boost Infineon's newly promoted 650 V high and low side gate driver
the silicon-on-isolator (SOI) technology.
Intended audience
This application note is intended for all technical specialists likely to evaluate the 650 V SOI gate drivers for
general applications.
