Getting started with X-NUCLEO-IHM08M1 low-voltage BLDC motor
driver expansion board based on STL220N6F7 for STM32 Nucleo
Introduction
The X-NUCLEO-IHM08M1 is a three-phase brushless DC motor driver expansion board based on
STripFET™ F7 Power MOSFET STL220N6F7 for STM32 Nucleo. It provides an affordable and easy-touse solution for driving a three-phase brushless DC motor in your STM32 Nucleo project. The XNUCLEO-IHM08M1 is compatible with the ST morpho connector and supports further stacking of
additional boards on a single STM32 Nucleo board. You can also mount the Arduino™ UNO R3
connector.
The X-NUCLEO-IHM08M1 is fully configurable and ready to support different closed loop control
scenarios based on sensorless or sensor mode control, and it is compatible with three-shunt or singleshunt current sense measuring. The L6398 IC driver used on this STM32 Nucleo expansion board is a
single-chip half bridge gate driver for the N-channel power MOSFET. This combination of the L6398
gate driver and the STL220N6F7 Power MOSFET forms a high current power platform for BLDC
motors, while the digital section supported by the STM32 Nucleo board allows for a 6-step or FOC
control algorithm solution, which you can select via the firmware. This document describes how to
configure the X-NUCLEO-IHM08M1 expansion board to operate with STM32 Nucleo board.

2.1
System architecture
A generic motor control system can be basically schematized as the arrangement of three
main functional blocks (see System functional hardware blocks):
Control block accepts user commands to drive a motor. The X-NUCLEO-IHM08M1 is
based on the STM32 Nucleo board, which provides all the digital signals for effective
motor driving control.
Power block is based on the 3-phase inverter topology. The core of the power block
is the embedded L6398 driver, which contains all the necessary active power and
analog components to perform low voltage PMSM motor control.
Motor the X-NUCLEO-IHM08M1 is able to proper drive a low voltage BLDC/PMSM
motor.
This section describes how to set up different hardware parts before writing and executing
an application on the STM32 Nucleo board with the low-voltage BLDC motor driver
expansion board.
Figure 2: System functional hardware blocks
2.2
Building the system
The X-NUCLEO-IHM08M1 expansion board (Power block in the figure above) is a
complete hardware development platform for the STM32 Nucleo board allowing effective
evaluation of motor control solutions for single BLDC/PMSM motors. For regular board
operation, please follow the steps below:
1.
6/29
Plug the expansion board on an STM32 Nucleo main board (Control block) through
the ST morpho connector; there is only one position allowed for this connection.
Ensure that the blue (B1) and black (B2) buttons on the STM32 Nucleo board are not
covered, as shown below.

Getting started
Figure 3: X-NUCLEO-IHM08M1 plugged on STM32 Nucleo board
The interconnection between the STM32 Nucleo board and the X-NUCLEO-IHM08M1
expansion board is designed for full-compatibility with a wide range of STM32 Nucleo
boards without any solder bridge modifications, except for the removal of resistor R60 on
the X-NUCLEO-IHM08M1 board if the NUCLEO-F401RE board is used and X-CUBESPN8 firmware is installed.
The stacked system is ready to operate with the connection of a BLDC/PMSM motor. For
correct use, please follow the hardware and software settings. For software details, please
refer to X-CUBE-SPN8 documentation available on www.st.com.
1.
2.
3.
Connect the three motor wires U,V,W to the J16 connector.
To select the control algorithm (6-step or FOC), ensure no voltage supply is
connected.
On the STM32 NUCLEO board, set jumpers: JP1 open, JP5 (PWR) on E5V side, JP6
(IDD) closed.On the X-NUCLEO-IHM08M1 expansion board, set jumpers: J9 open,
JP3 closed.
For 6-step control (X-CUBE-SPN8 FW), set jumpers: JP1 and JP2 open, J5&J6
on the 1-Sh side. Keep capacitor C5 mounted; in case of poor motor current
regulation during startup, reduce its value.
For FOC control (STSW-STM32100 FW), set jumpers: JP1 and JP2 closed,
J5&J6 on the 3-Sh side. Remove capacitors C3, C5 and C7.
Connect the DC supply voltage to the J1 connector. An external power supply is
required to power up the power board and the STM32 Nucleo board. Be sure to
supply the right power for the connected motor; (e.g., max. 12V and 2A for the
BR2804 motor).

UM1996
When using a different motor rated greater than 12 V, keep jumper J9 on the
power board open before applying power-on voltage at J1 to avoid damaging the
Nucleo board. To supply the STM32-NUCLEO via usb, connect jumper JP5
between PIN 1 and PIN2. For further details on Nucleo settings, refer to UM1724
at http://www.st.com.
2.2.1
Hardware settings
By default, the X-NUCLEO-IHM08M1 provides the power supply voltage for STM32 Nucleo
board (+5V on E5V) independently through the power voltage applied at the J1 connector.
Removing resistor R170 on the expansion board, you can disconnect internal voltage
regulation and select jumper J9 to supply the STM32 Nucleo board directly from J1
connector (see Table 1: "Jumper settings") if, for instance, higher conversion efficiency is
required. For this last configuration please read the recommendation below.

Power section
4.1.1
L6398 gate driver and STL220N6F7 STripFET™ F7 Power MOSFET
The main section is based on:
1.
2.
L6398 single-chip half bridge gate driver for the N-channel power MOSFET - a highvoltage device manufactured with the BCD “OFF-LINE” technology. The high side
(floating) section is designed to handle a voltage rail of up to 600 V and the logic
inputs are CMOS/TTL compatible down to 3.3 V for easy microcontroller/DSP
interfacing.
STL220N6F7 260 A – 60 V N-channel Power MOSFET – based on the STripFET™
F7 technology with an enhanced trench gate structure that results in very low on-state
resistance, while also reducing internal capacitance and gate charge for faster and
more efficient switching. It features:
Among the lowest RDS(on) on the market: 0.0014 Ω
Excellent figure of merit (FoM)
Low Crss/Ciss ratio for EMI immunity
High avalanche ruggedness
Together, these devices form the high current power platform for the BLDC motor. The
main supply voltage is provided through an external connector (J1) and you can set jumper
(J9) to choose whether the digital section (STM32 Nucleo board) is supplied via USB (USB
type A to Mini-B USB cable) or through the expansion board. By default, the STM32 nucleo
expansion board provides the supply voltage to the STM32 Nucleo board through its
internal voltage regulator, but you can choose to supply it directly from the J1 power
connector if higher conversion efficiency is required and if the input voltage is lower than 12
V DC (see Table 1: "Jumper settings").

4.1.2
Overcurrent detection (OCP) and current sensing measurement
Over Current Protection (OCP) is implemented by hardware with a detection circuit. The
current is compared with an embedded current reference (by the MCU) and the output
generates a fault condition at the BKIN pin that goes to ground. This pin, connected to
STM32 Nucleo board (BKIN Timer function), detects this condition and immediately
disables the driving signals (see the schematic below).
Figure 12: X-NUCLEO-IHM08M1 – OCP circuit
The current sensing inputs (refer to the following three schematics) are connected to the
sensing resistors and you can choose between a three-shunt or single-shunt configuration
through jumpers J5 and J6 (see Table 1: "Jumper settings").

The board must be configured according to the motor control algorithm:
for 6-step control, keep capacitor C5 mounted but, in case of poor motor

for FOC control, remove capacitors C3, C5 and C7.

The X-NUCLEO-IHM08M1 expansion board implements the Hall/Encoder sensor detecting
circuit for speed measurement, the schematic for which is given in the figure below. The
motor sensor pin, through the J3 connector and an analog circuit, are connected to the
STM32 Nucleo board in order to determine motor spin; a +5 V and GND are also provided
to power the sensors. Jumper JP3 is available for sensors that require external pull-up (see

BEMF detection circuit
The X-NUCLEO-IHM08M1 expansion board provides two hardware solutions for motor
position measurement: one based on sensors and the other based on sensorless
detection.
In 6-step driving mode, one of the three phases is left in the high-impedance state and we
can detect BEMF zero-crossing events by comparing the voltage of this phase with the
center-tap voltage. This signal is acquired through an analog circuit embedded on the
board, as shown below.
Figure 17: X-NUCLEO-IHM08M1 – BEMF detection circuit
The X-NUCLEO-IHM08M1 expansion board provides the hardware for bus voltage sensing
and temperature measurement. This signal is acquired with a resistor divider and with an
embedded NTC (placed close to STL220N6F7 Power MOSFET), as shown below.
