Evaluation board for SiC MOSFET SCT4036KW7
HB2637L-EVK-301
This manual explains how to use the evaluation board HB2637L-EVK-301 with ROHM’s 4
th
generation SiC MOSFETs with TO-263-7L package.
The evaluation board is configured in a half bridge set up and thus allows evaluations in different operations modes such as buck, boost, syn-
chronous buck/boost and inverter operations. The board is equipped with two SiC MOSFETs (SCT4036KW7), isolated gate driver
BM61S41RFV-C, isolated power supply required for the gate driver, LDO for 5V supply and easy to interface connectors for PWM signals.
This user guide contains a schematic of the evaluation board, a Bill of Material list (BOM) and also description on the overall functioning of the
evaluation board. Additionally, the user guide contains important notices and warnings that need to be carefully reviewed prior to use of the board.
Important Notice
This evaluation board is intended for
product evaluation in a research and development context only
and is not intended for
resale to end consumers and it is not authorized for end customer or household use. This board may not comply with CE or similar
standards (including, but not limited to the EMC directive 2004/EC/108) and may not fulfil other requirements of the country it will
be operated in by the user. The user shall ensure that the evaluation board will be handled in a way that is compliant with all the
standards and regulations in the country it will be operated in.
The evaluation board provided here has only been subjected to functional testing under typical load conditions. The design of this
evaluation board is tested by ROHM only as described in the user guide for this board. The design is not qualified in terms of
safety requirements, manufacturing and operation over the entire operating temperature range or lifetime.
This evaluation board may only be used by authorized personnel that is properly trained in recognizing and dealing with
the dangers of testing high voltage equipment and generally experimenting with high voltage circuits.
Ensure you review
this user guide as it contains important safety warnings. At all times, follow the applicable safety rules for dealing with high voltages.
Do not connect or disconnect any wires or probes to the evaluation board, while it is connected to a power supply. Take care that
capacitors on the board have discharged fully before touching any part of the board. Always place the evaluation board under
appropriate covers, such as in a Perspex box, to protect against accidental touching of high voltage parts BEFORE applying a
voltage supply to the board.
This evaluation board does not have a short circuit protection function for the evaluation device.
Therefore, even with the normal evaluation method, if the usage deviates from the electrical specifica-
tions (maximum current, etc.) of the evaluation device selected by the customer, the device may be
severely damaged with a popping sound. Therefore, never use the evaluation board in a way that de-
viates from the specifications of the evaluation device. Also, take precautions to prevent fragments
from scattering and use protective equipment in case severe damage occurs.
