1Safety precautions

Please note the following warnings regarding the hazards associated with development systems.

Table 1 Safety precautions

Caution: Only personnel familiar with the drive, power electronics and associated

machinery should plan, install, commission and subsequently service the system. Failure to

comply may result in personal injury and/or equipment damage.

Caution: The heat sink and device surfaces of the evaluation or reference board may

become hot during testing. Hence, necessary precautions are required while handling the

board. Failure to comply may cause injury.

Caution: REF-Vacuum-C101-2ED reference board contains parts and assemblies sensitive to

Electrostatic Discharge (ESD). Electrostatic control precautions are required when installing,

testing, servicing or repairing the assembly. Component damage may result if ESD control

procedures are not followed. If you are not familiar with electrostatic controlprocedures, refer

to the applicable ESD protection handbooks and guidelines.

Caution: A drive that is incorrectly applied or installed can lead to component damage or

reduction in product lifetime. Wiring or application errors such as undersizing the motor,

supplying an incorrect or inadequate DC supply, or excessive ambient temperatures may

result in system malfunction.

Caution: REF-Vacuum-C101-2ED reference board is shipped with packing materials that need

to be removed prior to installation. Failure to remove all packing materials that are

unnecessary for system installation may result in overheating or abnormal operating

conditions.

2Introduction

The REF-Vacuum-C101-2ED is part of the iMOTION™ reference design kits. It is designed to provide ready-to-

use, low-voltage and high-speed vacuum solutions based on Infineon’s thin-film SOI technology and advanced

motion control engine (MCE 2.0) technology. It allows fast prototyping and fast time to market. The board is

equipped with all assembly groups for sensorless field-oriented control (FOC), and reserved interface for three

digital Hall sensors, so that it can be extended to other low-voltage and high-current motor applications.

The block diagram of the REF-Vacuum-C101-2ED is depicted in Figure 1, which contains iMOTION™ controller

IMC101T, 3 mOhm 40 V OptiMOSTM, and 2ED2304S06F half-bridge gate driver with integrated bootstrap diode.

This reference design includes:

-Gate driver IC for MOSFET

-Anti-reverse connection protection

-12 V & 3.3 V auxiliary power supply

-VSP speed command potentiometer

-Over temperature and overcurrent protection

-Turnkey version sensor less & sensor FOC control

The REF-Vacuum-C101-2ED reference design is available through regular Infineon distribution partners as well

as on Infineon's website. The main features of this board are described in this document, whereas the

remaining paragraphs provide information to enable the customers to copy, modify and qualify the design for

production according to their own specific requirements.

An 18 V, 250 W vacuum motor is used for the default DEMO function, whose maximum speed is 100 kRPM.

Please note that motor parameters need to be double-checked in MCEWizard if a different motor is used.
