STEVAL-IHM012V1 evaluation board
The STEVAL-IHM012V1 evaluation board was developed to demonstrate ST’s solution for
low-end cordless tools such as cordless drills or screwdrivers but it can be a good starting
point for designing all the applications where it need to drive a low voltage DC brush motor.
The board is shown in
On the left side there are two connectors:
On the right side there are two connectors:
●
That potentiometer emulates the standard push button mounting in the case of a cordless
drill to regulate the rate of the motor.
●
With easy adjustments the STEVAL-IHM012V1 can drive DC brush motors 7.2 - 18 V. The
maximum power range used on the evaluation board depends on the motor driven
(maximum handling current) and relative Power MOSFET mounted on the board (see
Section 4: Application design
This evaluation board is set up to work with a 7.2 DC brush motor (Imax is set at 8 A).
the supply current for the microcontroller is obtained from the input voltage. The Zener
regulator circuit in this application is designed to ensure the minimum voltage for the
microcontroller operations also if the battery voltage is the minimum allowed.

Warning:
the mains connector for battery voltage supply
the connector for the DC Brush motor
Before downloading firmware in the microcontroller, ensure
that jumpers J1 and J2 are NOT present before the input
voltage is connected. Under normal conditions these
jumpers must be present before the input voltage is
connected.
