ST STEVAL-PTOOL2V1, Getting Started, Page: 1 / 28

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 V
DC
) input voltage and includes a power supply stage with
the VIPER013BLS in buck configuration to ge12 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 ).
