STSPIN32F0 motor control SiP family
Added two 250V products and two 600V products
Provides single-shunt and three-shunt FOC examples


STMicroelectronics announced on the 25th that it has added four new devices to its STSPIN32F0 motor control SiP (System-in-Package) family that simplify the design of mains-powered industrial equipment and home appliances such as corded power tools, drives, pumps, fans, and compressors.

The 250V △STSPIN32F0251 △STSPIN32F0252 and 600V △STSPIN32F0601 △STSPIN32F0602 integrate three-phase gate drivers and an STM32F0 Arm Cortex-M0 MCU to simplify high-voltage BLDC (Brushless DC) motor drive design.

Commonly used control algorithms and application examples are also provided, including single-shunt and three-shunt Field Oriented Control (FOC), as well as conventional sensor-based single-shunt and six-step sensorless control.

All four devices are pin-compatible, allowing hardware and firmware to be reused across products operating at 110V AC and 250V AC. Supports standby mode to minimize power consumption when idle.

All gate drivers integrate protection circuitry, including cross-conduction prevention and dead-time insertion, as well as a bootstrap diode. Furthermore, UVLO is integrated into both the lower and upper drive sections to prevent power switches from operating under low-efficiency or hazardous conditions. The devices also support the patented smartSD (ShutDown) function, which operates at high speed to protect against overload and overcurrent.

The four devices integrate a 48MHz STM32F0 MCU, allowing customers to build applications based on the STM32 development ecosystem. 4KByte SRAM and 32KByte Flash provide data and code storage, while analog and digital peripherals include a 12-bit ADC with up to 10 channels, six general-purpose timers, 21 GPIO (general-purpose I/O) pins, and I2C, UART, and SPI ports. An integrated bootloader allows firmware updates in the field.

Starting with version 5.4.1, four inverter evaluation boards are available, compatible with the X-CUBE-MCSDK. These tools simplify drive development by leveraging single-shunt and three-shunt control.

Additionally, the 600V EVSPIN32F0601S1, EVSPIN32F0601S3, EVSPIN32F0602S1, and 250V EVSPIN32F0251S1 include a power supply stage and an integrated MOSFET output stage with dual footprint flexibility, allowing them to replace devices supplied with other MOSFETs or IGBTs in DPAK or PowerFlat packages.

The detachable STLINK debugger allows configuration and firmware debugging using standard STM32 tools. SWD (Single-Wire Debug) and UART connectors are also available.

The STSPIN32F0251, STSPIN32F0252, STSPIN32F0601, and STSPIN32F0602 are available in a 10 mm × 10 mm TQFP package and are priced from $1.84 to $2.09 in quantities of 1,000.
