EVAL-M7-D112T user guide
iMOTION™ evaluation board for smart driver s
About this document
Scope and purpose
This user guide provides an overview of the evaluation board EVAL-M7-D112T, including its main features, key-
technical data, pin assignments, and mechanical dimensions.
EVAL-M7-D112T is an iMOTION™ application design kit based on Infineon's IMD112T smart driver. This board
features and demonstrates Infineon's advanced motion control engine technology for permanent magnet
synchronous motors drive over the full speed range, combined with a fully integrated, 3-phase high-voltage
gate driver, and a 5 V voltage regulator in a very compact QFP 40-pins package. A boost power factor correction
(PFC) control function is also integrated into IMD112T.
The evaluation board EVAL-M7-D112T has been developed to support users during their first steps designing
applications in which running a permanent magnet motor via a sensor less, sinusoidal, field-oriented control,
and PFC function are necessary.
Intended audience
This evaluation board is intended for all technical specialists familiar with motor control and power electronics
converter systems.
Evaluation board
This board is to be used during the design-in process for evaluating and measuring characteristic curves, and
for checking datasheet specifications. This board is intended to be used under laboratory conditions only.
Note:
PCB and auxiliary circuits are NOT optimized for final customer design.
