STMicroelectronics STSPIN32F0252
STSPIN32F0252 - 250V three-phase controller with MCU
The STSPIN32F025x is a system in package providing an extremely integrated solution suitable for driving three-phase applications.
It embeds an MCU (STM32F031x6x7) featuring an ARM® 32-bit Cortex®-M0 CPU and a 250V triple half bridge gate driver, able to drive N-channel power MOSFETs or IGBTs.
A comparator featuring advanced smartSD function is integrated in the device, ensuring fast and effective protection against overload and overcurrent.
The high-voltage bootstrap diodes are also integrated, as well as anti cross-conduction (interlocking), deadtime and UVLO protection on both the lower and upper driving sections, which prevents the power switches from operating in low efficiency or dangerous conditions. Matched delays between low and high-side sections guarantee no cycle distortion.
The integrated MCU allows performing FOC, 6-step sensorless and other advanced driving algorithm including the speed control loop.
It has WR and RD protection for embedded flash memory to prevent unwanted writing and reading, and it can be put in standby mode to reduce the power consumption.
The MCU provides 21 general-purpose I/O ports (GPIO) with 5 V tolerant capability, one 12-bit analog-to-digital converter with up to 10 channels performing conversions in a single-shot or scan modes, 6 synchronizable general-purpose timers and supports an easy to use debugging serial interface (SWD).
All of the integrated features of STSPIN32F025x make design of the application PCB easier, and result in reduced PCB area consumption, bill of material and overall application cost.

STEVAL-PTOOL2V1 - Compact reference design for battery-operated brushless power tools based on STSPIN32F0252
The STEVAL-PTOOL2V1 BLDC driver reference design is tailored for battery-operated power tools using 8S to 15S battery packs. It is based on the STSPIN32F0252 motor controller with embedded 3-phase, 250 V gate driver and low-power STM32 MCU. The power stage is based on the STL130N8F7 power MOSFETs or any similarly rated device in a PowerFlat 5x6 package.
The board implements single shunt sensing topology with both field-oriented control.
(FOC) and sensored or sensorless 6-step control supported for driving permanent magnet synchronous motors (PMSM) and brushless DC (BLDC) motors.
The companion 6-step STSW-PTOOL2V1 firmware is ready to use with position feedback from phase Hall-effect sensors.
This reference design can deliver up to 19 A continuous current with very good thermal dissipation performance thanks to the mounted heatsink. It is compatible with a wide input voltage range from 20 to 72 VDC, and includes an auxiliary power stage with the VIPER013 in buck configuration to generate +12V and +3.3V supply voltage required by the application.
The STEVAL-PTOOL2V1 features a potentiometer for speed variation and protection features include thermal shutdown, undervoltage lockout, and overcurrent protection.
This compact 80 mm x 58 mm design is ideal for power tools and any similar battery-operated applications in terms of architecture, rating and performance.
