Type: User manual

Introduction

The X-NUCLEO-IHM15A1 dual brush DC motor driver expansion board is based on the STSPIN840 for STM32 Nucleo.

It provides an affordable and easy-to-use solution for the implementation of compact motor driving applications such as thermal

printers, robotics and toys.

Thanks to the parallel operation, it can be easily converted to a single brush DC driver with double current capability.

The current limiters and complete set of protection features make it suitable for rugged applications.

The X-NUCLEO-IHM15A1 is compatible with the Arduino UNO R3 connector and most STM32 Nucleo boards.

2Safety precautions

Danger:

Some of the components mounted on the board could reach hazardous temperature

during operation.

While using the board:

• Do not touch the components

• Do not cover the board

• Do not put the board in contact with flammable materials or with materials releasing smoke when heated

• After operation, allow the board to cool down before touching it

3Getting started

The X-NUCLEO-IHM15A1 expansion board is a dual brush DC motor driver covering a wide range of

applications.

The maximum ratings of the expansion board are:

• power stage supply voltage (VS) from 7 to 45 V

• motor phase current up to 1.5 Arms

To start your project with the expansion board:

Step 1. Check the jumper position based on your configuration.

Step 2. Connect the X-NUCLEO-IHM15A1 to the STM32 Nucleo board through Arduino UNO R3 connectors

(CN5, CN6, CN8 and CN9).

Step 3. Supply the board through the input 5 (Vin) and 6 (GND) of the connector J1.

The D5 and D6 LEDs (red) turn on.

Step 4. Develop your application using the examples provided with the firmware library (X-CUBE-SPN15).

4.1 Selecting the STM32 Nucleo board

The X-NUCLEO-IHM15A1 expansion board offers native support for the following STM32 Nucleo development

boards:

•NUCLEO-F401RE

•NUCLEO-F334R8

•NUCLEO-F030R8

4.2 Adjusting the off-time and the thresholds of the current limiters

The STSPIN840 integrates two current limiters, one for each full bridge.

The bridge current is sensed through the voltage drop across an external shunt resistor connected between the

source of the low side power MOSFET (SENSEx pins) and the ground.

The current limiter compares the voltage of the SNSA and SNSB pins to the respective reference voltage pin

(REFA and REFB). When VSNSX > VREFX, the control logic turns on both the low-side MOSFETs of the power

stage for a period adjusted through the pull-down resistor connected to the TOFF pin.

In the X-NUCLEO-IHM15A1 board, both a trimmer and a PWM signal from the Nucleo board adjust the current

limit thresholds:

Ipeak =VREF

RSHUNT =

VDD ×Rtrim

Rtrim + 5.6 kΩ×PWMDC

0.34 Ω (1)

The R5 resistor adjusts the off-time of both limiters; the value mounted by default on the board sets a duration of

about 40 µs.
