Low voltage motor control demonstration board
based on ST7MC MCU
Introduction
The low-voltage motor control demonstration board (also referred to by its order code
STEVAL-IHM015V1) is a complete development platform for low-voltage motor control
applications. Based on a cost-effective, flexible and open design, it allows easy
demonstration of ST7MC capabilities to drive low-voltage synchronous motors. It includes
an ST7MC 8-bit microcontroller with a 16-Kbyte internal Flash memory. The STEVAL-
IHM015V1 comes with all the hardware necessary for developing motor control applications
based on ST7MC peripherals including a motor control peripheral (MTC) and serial
communication interface (SCI). The STEVAL-IHM015V1 uses an in-circuit communication
(ICC) standard interface to connect to the host PC via in-circuit debuggers/programmers
such as the in DART-STX board from Softec. The boardâs power stage is designed to
support up to 25 A and up to 48 V. With the included power MOSFET device STS8DNH3LL
in SO-8 package, the maximum input voltage is 30 V and the maximum current rating is 8 A.
The power supply stage can be easily configured to accept a wide range of input voltages.
