High Voltage Focus for New BLDC Drivers Launched by STMicroelectronics via STSPIN32
STMicroelectronics has expanded its motor control portfolio with the introduction of four new devices in the STSPIN32F0 family. These devices are designed for mains-powered home appliances and industrial equipment, simplifying high-voltage Brushless DC (BLDC) motor drives.
The new devices are pin compatible, allowing hardware and firmware to be reused in products for 110V AC and 250V AC operation. They also feature a patented fast-acting smart ShutDown (smartSD) function for overload and overcurrent protection, ensuring safety and reliability.
Each device offers 4KByte SRAM and 32KByte Flash for data and code storage, along with a rich set of analog and digital peripherals. These include a 12-bit ADC with up to 10 channels, six general-purpose timers, 21 general-purpose I/O (GPIO) pins, and I2C, UART, and SPI ports. The integrated STM32F0 Arm Cortex-M0 microcontroller allows users to leverage the rich STM32 development ecosystem.
The evaluation boards for these devices contain a power-supply stage and a populated MOSFET output stage with dual-footprint flexibility. Four inverter evaluation boards are available, compatible with X-CUBE-MCSDK and simplifying development of drives with single-shunt and three-shunt control.
The 600V and 250V evaluation boards are packaged as 10mm x 10mm TQFP devices and are available now. The 250V STSPIN32F0251 and STSPIN32F0252, and 600V STSPIN32F0601 and STSPIN32F0602 are the specific models introduced.
The devices also come with a detachable STLINK-debugger for configuration and firmware debugging. Popular control algorithms and application examples are provided, such as single-shunt and three-shunt field-oriented control (FOC), as well as traditional sensored single-shunt and 6-step sensorless control.
Moreover, the devices offer a standby mode to help minimize power consumption in idle conditions. The evaluation boards range in price from $1.84 to $2.09 for orders of 1000 pieces.
STMicroelectronics has priced these new devices competitively, making them accessible for a wide range of applications. The devices and evaluation boards are available since June 2024.
