ST STEVAL-PTOOL2V1 User manual

Introduction
The STEVAL-PTOOL2V1 is a ready-to-use reference design tailored for medium voltage power tools driven by 3-phase
brushless motors and supplied from 8S to 15S batteries. It can also effectively be used in other battery-operated applications
requiring similar architecture, rating and performance.
The STEVAL-PTOOL2V1 is based on the STSPIN32F0252 motor controller which embeds a 3-phase 250 V gate driver, a
Cortex®‑M0 STM32 MCU and STL130N8F7 MOSFETs.
The power stage can be populated with any power MOSFET with similar ratings and hosted in a powerFLAT 5x6 package.
The board has a single shunt sensing topology. Field-oriented control (FOC) and sensored or sensorless 6-step control
implementation allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors.
This reference design can deliver up to 19 A of continuous current with very good thermal dissipation performance thanks to the
mounted heat-sink. It is compatible with a wide range (from 20 to 72 VDC) input voltage and includes a power supply stage with
the VIPER013BLS in buck configuration to generate +12 V and +3.3 V supply voltage required by the application.
The STEVAL-PTOOL2V1 embeds a potentiometer for speed variation and is fully protected from thermal shutdown,
undervoltage lockout and overcurrent.
It comes in a compact layout of 80 x 58 mm and includes the STSW-PTOOL2V1 six-step companion firmware that uses the
position feedback from Hall effect sensors.
The STSW-PTOOL2V1 firmware can be debugged and configured through an external ST-LINK debugger (ST-LINK/V2-1 or ST-
LINK/V3MINI).

1.1 Safety precautions
Danger:
There is danger of serious personal injury, property damage or death due to electrical shock and
burn hazards if the kit or components are improperly used or installed incorrectly.
Warning:
• The kit is not electrically isolated from the high-voltage supply AC-DC input.
• The evaluation board is directly linked to the mains voltage. No insulation is ensured
between the accessible parts and the high voltage. All measurement equipment must be
isolated from the mains before powering the board.
• When using an oscilloscope with the evaluation board, it must be isolated from the AC line.
This prevents shock from occurring as a result of touching any single point in the circuit, but
does NOT prevent shock when touching two or more points in the circuit.
Caution: During assembly, testing, and operation, the evaluation board poses several inherent hazards, including bare
wires, moving or rotating parts and hot surfaces.
All operations involving transportation, installation, use and maintenance must be performed by skilled technical
personnel who is familiar with the installation, use and maintenance of power electronic systems.
Work area safety
• The work area must be clean and tidy
• Do not work alone when boards are powered
• Protect the area against any unauthorized access by putting suitable barriers and signs
• A system architecture that supplies power to the evaluation board must be equipped with additional control
and protective devices in accordance with the applicable safety requirements (i.e., compliance with technical
equipment and accident prevention rules)
Electrical safety
• Remove power supply from the evaluation board and electrical loads before performing any electrical
measurement
• Arrange measurement setup, wiring and configuration paying attention to high voltage sections
• Once the setup is complete, power the board
Danger:
Do not touch the evaluation board when it is powered or immediately after it has been
disconnected from the voltage supply as several parts and power terminals containing potentially
energized capacitors need time to discharge, and heat-sinks and transformers may still be very
hot.
The kit is not electrically isolated from the AC-DC input.
Personal safety
• Always wear suitable personal protective equipment, such as insulating gloves and safety glasses
• Take adequate precautions and install the board preventing accidental touch
• Use protective shields, such as insulating box with interlocks

3How to use the board
Step 1. Check the jumper position according to the target configuration (see Section 2 Hardware description
and configuration).
Step 2. Connect the motor phases to J6, J7 and J8 pads on the basis of the motor phase sequence.
Step 3. Supply the board through DC J4 (VBAT+) and J5 (VBAT-) pads.
Step 4. Develop your application using the STSW-PTOOL2V1 firmware example package as starting point.
3.1 Sensorless mode
To configure the STEVAL-PTOOL2V1 evaluation board for 6-step sensorless mode, BEMF network components
(R65, R66, R67) have to be mounted and the BEMF detection network must be enabled.
You have to set jumpers as follows:
• JP2 pins 1-2: closed, PA0 connected to BEMF phase U
• JP3 pins 1-2: closed, PA1 connected to BEMF phase V
• JP4 pins 1-2: closed, PA2 connected to BEMF phase W

4Hall/encoder motor speed sensor
The STEVAL-PTOOL2V1 evaluation board supports the digital Hall and quadrature encoder sensors for motor
position feedback.
Sensors can be connected to the STSPIN32F0252 through J2 connector as listed in the following table.
Table 4. Hall/encoder sensors and J2 connections
Name Pin Description
Hall1/A+ 1 Hall sensor 1/encoder out A+
Hall2/B+ 2 Hall sensor 2/encoder out B+
Hall3/Z+ 3 Hall sensor 3/encoder Zero feedback
VHALL 4 Sensor supply voltage (default VDD)
GND 5 Ground
A protection resistor of 1 kΩ is mounted in series with sensor outputs.
For sensors requiring external pull-up, three 10 kΩ resistors are already mounted on the output lines and
connected to VDD voltage.
Set jumper resistors (R43 and R44) to configure the power supply for sensor supply voltage as follows:
• R44 mounted, R43 unmounted → Hall sensors powered by VDD (3.3 V)
• R44 unmounted, R43 mounted → Hall sensors powered by VCC (12 V)
The STSPIN32F0252 MCU can decode Hall/encoder sensor outputs by configuring jumpers as follows:
• JP2 pins 2-3: closed, PA0 connected to Hall1
• JP3 pins 2-3: closed, PA1 connected to Hall2
• JP4 pins 2-3: closed, PA2 connected to Hall3

5Overcurrent detection and current sensing measurement
The STEVAL-PTOOL2V1 evaluation board implements overcurrent protection based on the STSPIN32F0252
integrated comparator.
The single shunt resistor measures the load current bringing the voltage signal associated to the load current and
amplified by U2B OpAmp to CIN pin (TP22). When the phase peak current exceeds the selected threshold, the
integrated comparator is triggered and all power switches are disabled until the current falls below the threshold
and the output disable time expires.

Current signal amplifying network
By default, the STEVAL-PTOOL2V1 evaluation board overcurrent threshold is set to IOC_typ = 36 A and the restart
time after fault detection is ~735 µs.
Overcurrent threshold can be modified by changing the amplifying circuit gain and offset, according to the
following formulas:
IOCtyp =VREFtyp ⋅1
5RSHUNT ⋅ Ra ⋅ G − VDD ⋅ Rb RSHUNT ⋅ Ra (1)
Where, based on default values:
VREF_typ = 460 mV, VDD = 3.3 V, RSHUNT = R25 = 3 mΩ and
Ra =R63//R61
R56 + R58 + R63/ /R61 = 0.81 R63 + ∞(2)
Rb =R58 + R56 / /R61
R63 + R58 + R56 / /R61 = 0 R63 + ∞ G = 1 + R60 R58 + R56 = 5.25 (3)
Therefore:
IOCtyp ≅36 A
The output disable time can be monitored on OD pin (TP17) and is determined by the time required to recharge
C10 capacitor up to VSSDh threshold, according to:
VSSDh = 3.8 V, VSSDI = 0.56 V, VOD = VCC =12 V
T2≅ C10 ⋅ R16 ⋅1nVSSDl − VOD
VSSDℎ− VOD (4)

6Bus voltage circuit
The STEVAL-PTOOL2V1 evaluation board provides the bus voltage sensing. This signal is set through voltage
dividers (R71 and R72) from motor supply voltage (VBAT) and sent to PA7 GPIO (ADC channel 7) of the
embedded MCU. The default voltage divider is set to 24.3.

7Hardware user interface
The STEVAL-PTOOL2V1 board provides a hardware user interface which consists of:
• a trimmer (TR1) to set the target speed
• SW1 switch to set motor spin direction
• SW2 switch to turn the board power supply on or off, thus reducing static consumption to 0 A via Q8 P-
channel MOSFET. If a continuous power supply is needed, for example, to load the firmware onto the MCU,
short J3 connector pins.
All above mentioned interfaces can be replaced by external inputs.
7.1 Detachable interface
If the on-board hardware user interface (SW1, SW2 and TR1) are not used, it is possible to detach the interface
section by breaking the PCB along the slot holes.
You can still program or debug STSPIN32F0252 by connecting an external ST-LINK/V2-1 to J11 SWD connector.
Figure 6. STEVAL-PTOOL2V1 detachable section
7.2 Turn on/off circuitry
The board offers the possibility of connecting or disconnecting the battery to the circuitry via an external switch
(J3), to reduce the quiescent consumption to a very low level.
As soon as the switch is closed, the motor can be driven as required by the control algorithm.
By closing the trigger switch, the Q8 PMOS gate is forced low, connecting the battery to the control circuitry.

GPIO input (trigger monitor)
GPIO output (keep-alive circuit)
7.2.1 Keep-alive circuit
As soon as the Q8 PMOS connects the battery to the buck regulator, the power-up sequence starts, and VCC and
VDD are provided to the STSPIN32F0252 driver and MCU, respectively.
When the MCU is operative, the PMOS can be kept turned on using Q7 NMOS, which acts as an MCU driven
switch in parallel with the external trigger switch. Thus, the firmware takes control of the connection between the
battery and the STSPIN32F0252 allowing the code to perform a safe switch-off (for example, by applying a brake
sequence to the motor).
Note: Set the GPIO output (PC14) HIGH at MCU initialization.
7.2.2 External trigger status detection
While the STSPIN32F0252 is supplied by the keep-alive circuit, the actual status of the external trigger switch
must be constantly monitored to execute the shutdown sequence when it is released.
The monitoring GPIO (PC15) is connected to the switch through D20 diode. As long as the switch is closed, the
GPIO is forced low through D20. Releasing the switch, D20 is no more polarized and the GPIO is pulled up by
R49 resistor. Therefore, setting an interrupt on the rising edge of PC15 allows detecting the trigger release and
stop the motor.
