STMicroelectronics' motor drive technology

STMicroelectronics (ST) is one of the world's largest semiconductor companies with a broad product line and a world leader in many areas. In the Chinese market, ST's STM32 microcontrollers, set-top box chips and other technologies are well known. Today we are talking about ST's STSPIN series of motor drive products, which is one of ST's important businesses.

According to Mr. David Lucchetti, Director of Application for Smart Power, IPAD, and Protection Devices Products Division of STMicroelectronics Asia Pacific, ST has more than 30 years of experience in the field of motors, with core BCD technology, independent production, and its own supply chain. Any type of motor with a complete mass market ecosystem.

Here is a brief explanation of BCD technology. BCD is an abbreviation for bi-polar, CMOS, DMOS. The bi-polar bipolar technology is analog, the CMOS is digital, and the DMOS is power. The BCD process integrates a bipolar device with precise analog function, a digitally designed CMOS device, and a high-voltage, high-power DMOS device on the same chip, which has the advantages of high integration and low power consumption. BCD technology is the cornerstone of ST's motor drive technology.

ST packaged the driver chip and MCU to form the STSPIN32F0 product line. This is based on the Cortex-M0 core STM32 microcontroller plus three-phase half-bridge driver, and also integrates 12VLDO and 3.3VDC-DC regulators. This integrated design not only saves space but also speeds up the development process.

In addition to the system-level packaging technology mentioned earlier, STSPIN's device package is also comprehensive, including DIP, PowerSO, HTSSOP, QFP, QFN and custom QFN. Compared with ST's 30 years of experience in motor technology, ST has more than 50 years of experience in packaging, making ST's motor drive products long life cycle, high power dissipation, and adapt to harsh environments, especially suitable for various industries. Field applications.

Finally, what can STSPIN do specifically? Mr. Lucchetti said that when you think of STSPIN, you can think of fans, textile machinery, electronic valves, industrial automation, toys and game consoles, assembly machines, HID controls, medical equipment, power tools, stage lighting, cameras, ATMs, etc. There are also the most popular 3D printing, robots, drones and so on. In short, it means that STSPIN is almost omnipotent, you can choose it right.
