STMicroelectronics STSPIN32F0251
STSPIN32F0251 - 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.

EVSPIN32F0251S1 - 3-phase inverter based on STSPIN32F0251
The EVSPIN32F0251S1 board is a 3-phase complete inverter based on the STSPIN32F0251 controller, which embeds a 3‑phase 250 V gate driver and a Cortex®‑M0 STM32 MCU. The power stage features STD17NF25 MOSFETs, but can be populated with any IGBT or Power MOSFET in DPAK or powerFLAT 6x5 package.
The board has a single-shunt sensing topology, and both the field-oriented control (FOC) and sensored or sensorless 6‑step control can be implemented. This allows driving permanent magnet synchronous motors (PMSMs) and brushless DC (BLDC) motors.
The evaluation board is compatible with a wide range input voltage from 20 V to 120 V DC/AC, and includes a power supply stage with the VIPER013BLS in buck configuration to generate +15 V and +3.3 V supply voltage required by the application.
Debug and configuration of FW can be performed with standard STM32 tools through the detachable STLINK‑debugger. SWD and UART TX‑RX connectors are also available.
