About this document
Scope and purpose
This document describes the usage of the Motor control shield for BTN9970 and BTN9990 V1.2. The board can
be connected to an Arduino UNO board.
Intended audience
This document is intended for electronic engineers who want to evaluate a high current PMOS / NMOS half
bridge with integrated driver.
Evaluation board
This board can be used during design in phase for customer projects, for evaluation and measurement of
BTN9970 / BTN9990 device behavior.
PCB and auxiliary circuits are not optimized for final customer design.

Important notice
Important notice
"Evaluation boards and reference boards” mean products embedded on a printed circuit board (PCB) for
demonstration and / or evaluation purposes, which include, without limitation, demonstration, reference and
evaluation boards, kits and design (collectively referred to as “reference board”).
Environmental conditions have been considered in the design of the evaluation boards and reference boards
provided by Infineon Technologies. The design of the evaluation boards and reference boards has been tested
by Infineon Technologies only as described in this document. The design is not qualified in terms of safety
requirements, manufacturing and operation over the entire operating temperature range or lifetime.
The evaluation boards and reference boards provided by Infineon Technologies are subject to functional
testing only under typical load conditions. Evaluation boards and reference 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 and reference boards are not commercialized products, and are solely intended for
evaluation and testing purposes. In particular, they may not be used for reliability testing or production. The
evaluation boards and reference boards may therefore not comply with CE or similar standards (including but
not limited to the EMC Directive 2004/EC/108 and the EMC Act) and may not fulfill other requirements of the
country in which they are operated by the customer. The customer must ensure that all evaluation boards and
reference boards will be handled in a way which is compliant with the relevant requirements and standards of
the country in which they are operated.
The evaluation boards and reference boards as well as the information provided in this document are
addressed only to qualified and skilled technical staff, for laboratory usage, and must be used and managed
according to the terms and conditions set forth in this document and in other related documentation supplied
with the respective evaluation board and reference board.
It is the responsibility of the customer’s technical departments to evaluate the suitability of the evaluation
boards and reference boards for the intended application, and to evaluate the completeness and correctness of
the information provided in this document with respect to such application.
The customer is obliged to ensure that the use of the evaluation boards and reference boards does not cause
any harm to persons or third-party property.
The evaluation boards and reference boards and any information in this document is provided "as is" and
Infineon Technologies disclaims any warranties, express or implied, including but not limited to warranties of
non-infringement of third-party rights and implied warranties of fitness for any purpose, or for merchantability.
Infineon Technologies may not be responsible for any damages resulting from the use of the evaluation boards
and reference boards and/or from any information provided in this document. The customer is obliged to
defend, indemnify and hold Infineon Technologies harmless from and against any claims or damages arising
out of or resulting from any use thereof.
Infineon Technologies reserves the right to modify this document and/or any information provided herein at
any time without further notice.

Safety precautions
Safety precautions
Note: Please note the following warnings regarding the hazards associated with development systems.
Table 1 Safety precautions
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.
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.
The evaluation or 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 control procedures,
refer to the applicable ESD protection handbooks and guidelines.
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 AC supply, or excessive ambient temperatures may result in
system malfunction.
Warnings
Due to technical requirements products may contain dangerous substances. For information on the types in
question please contact your nearest Infineon Technologies office.
Except as otherwise explicitly approved by Infineon Technologies in a written document signed by authorized
representatives of Infineon Technologies, Infineon Technologies’ products may not be used in any applications
where a failure of the product or any consequences of the use thereof can reasonably be expected to result in
personal injury.
