2.2 Circuit description
The STEVAL-SPIN3202 evaluation board provides a complete single-shunt six-step
solution consisting of an STSPIN32F0A (advanced BLDC controller with an embedded
STM32 MCU) and a triple half-bridge power stage with the NMOS STD140N6F7.
The STSPIN32F0A autonomously generates all the required supply voltages starting from
the motor supply: the internal DC/DC buck converter provides 3.3 V and the internal linear
regulator provides 12 V for the gate drivers.
The current feedback signal conditioning is performed through the operational amplifiers
embedded in the device and an internal comparator performs overcurrent protection via the
shunt resistor.
Two user buttons, two LEDs and a trimmer are available to implement simple user
interfaces (e.g., starting/stopping the motor and set target speed).
The STEVAL-SPIN3202 evaluation board supports the quadrature encoder and digital Hall
sensors for motor position feedback. It also provides the circuitry to sense the motor BEMF
(sensorless operation).
The board includes an ST-LINK-V2 which allows the user to debug and download firmware
without any extra hardware.
The board also supports sensored or sensorless Field Oriented Control algorithm with
single-shunt sensing.
2.2.1 STEP/FOC selection
The user can select between six-step and Field Oriented Control modes by selecting
different jumpers on the board.
By default, the six-step mode is selected as per the following configuration:
jumper connected on J12 open and jumper J11 closed;
jumper connected on JP8 between pin 1 and 2 (6 STEP position).
The Field Oriented Control mode is selected as follows:
jumper connected on J12 closed and remove jumper from J11;
jumper connected on JP8 between pin 2 and 3 (FOC position).

2.2.2 Hall/encoder_connector motor speed sensor
The STEVAL-SPIN3202 evaluation board supports the digital Hall and quadrature encoder
sensors as motor position feedback.
The sensors can be connected to the STSPIN32F0A by closing jumpers JP5, JP6 and JP7
(open by default).
When JP5, JP6 and JP7 are closed (Hall/encoder mode), JP9, JP10 and
JP11should be respectively open (BEMF sensing mode).
The Hall sensor/encoder should be connected to J4 as per the following table.

A protection resistor of 1 kΩ is mounted in series with the sensor outputs.
For sensors requiring an external pull-up, three 10 kΩ resistors are already mounted on the
output lines and connected to the VDD voltage. On the same lines, a footprint for pull-down
resistors is also available.
The jumper JP3 selects the power supply for the sensor supply voltage:
jumper between pin 1 and pin 2: Hall sensors powered by V
USB
(5 V)
jumper between pin 1 and pin 2: Hall sensors powered by VDD (3.3 V)
2.2.3 Overcurrent detection and current sensing measurement
The STEVAL-SPIN3202 evaluation board implements overcurrent protection based on the
STSPIN32F0A integrated OC comparator.
The shunt resistor measures the load current. Resistors R26 and R27 bring the voltage
signal to the OC_COMP pin. When the peak current flowing though the shunt exceeds the
selected threshold, the integrated comparator is triggered and all the high side power
switches are disabled.
The current threshold of the STEVAL-SPIN3202 varies according to the STSPIN32F0A OC
threshold as listed in the following table.

2.2.4 Bus voltage sensing circuit
The STEVAL-SPIN3202 evaluation board provides the bus voltage sensing. This signal is
set through a voltage divider by the motor supply voltage (VBUS, R10 and R16) and sent to
the PB1 GPIO (the ADC channel 9) of the embedded MCU. The signal is also available on
the TP6.
2.2.5 Hardware user interface
The board provides the following hardware user interface:
potentiometer (R6 setting, for example, the target speed)
switch SW1 (to reset STSPIN32F0A MCU and ST-LINK V2)
switch SW2 (user button 1)
Switch SW3 (user button 2)
LED DL3 (user LED 1, turned on when the user 1 button is pressed too)
LED DL4 (user LED 2, turned on when the user 2 button is pressed too)
2.2.6 Debug
The STEVAL-SPIN3202 evaluation board embeds an ST-LINK/V2-1
debugger/programmer.
The ST-LINK features:
USB software re-enumeration
virtual com port interface on USB connected to the STSPIN32F0A (UART1) PB6/PB7
pins
mass storage interface on USB
The ST-LINK is supplied by the host PC through the USB cable connected to the board.
The LED LD1 provides ST-LINK communication status information:
Red LED flashing slowly: at power-on before USB initialization
Red LED flashing quickly: following the first successful communication between the
PC and ST-LINK/V2-1 (enumeration)
Red LED ON: the initialization between the PC and ST-LINK/V2-1 is complete
Green LED ON: successful target communication initialization
Red/green LED flashing: during communication with target
Green ON: communication successfully completed
The reset function is activated by removing the jumper J8.
