This application note provides an overview of the evaluation board Eval-M5-E1B1245N-SiC including its main features, key data, pin assignments and mechanical dimensions.

Eval-M5-E1B1245N-SiC is a complete evaluation board including a 3-phase SiC power module for motor drive applications. In combination with control boards equipped with the M5 32-pin interface connector such as the XMC DriveCard 4400, it features and demonstrates Infineon’s CoolSiC™ MOSFETs in motor drives.

The evaluation board Eval-M5-E1B1245N-SiC was developed to support customers during their first steps designing applications with the sixpack power module FS45MR12W1M1_B11. The module has a rated blocking voltage of 1200 V at a typical on-state resistance of 45 mOhm. It is optimized for motor drive applications with a very high-frequency switching operation.

The Eval-M5-E1B1245N-SiC evaluation board is part of the iMOTION™ Modular Application Design Kit for motor drives (iMOTION™ MADK).

The MADK platform is intended for use at various power stages with different control boards. These boards can easily be interfaced via the iMOTION™ MADK-M5 32-pin interface connector to control boards such as the XMC DriveCard 4400 or XMC DriveCard 1300.

This evaluation board is designed as an easy-to-use power stage based on Infineon’s 3-phase power modules. The board is equipped with shunts in the phase output enabling the implementation of sensorless control. It provides a three-phase AC connector, EMI filter, rectifier and a 3-phase output for connecting the motor. The power stage also contains isolated current, voltage and temperature sensing circuits.

The Eval-M5-E1B1245N-SiC evaluation board is available via regular Infineon distribution partners as well as on Infineon’s website. The features of this board are described in the design feature chapter of this document. The remaining paragraphs provide information enabling customers to copy, modify and qualify the design for production according to their own specific requirements.

Environmental conditions were considered in the design of the Eval-M5-E1B1245N-SiC. The design was tested as described in this document, but not qualified in terms of safety requirements, manufacturing and operation over the entire operating temperature range or lifetime. The boards provided by Infineon are subject to functional testing only.

Evaluation boards are not subject to the same procedures as regular products regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD). Evaluation boards are intended to be used under laboratory conditions and by trained specialists only.
