ST STSPIN32F0252TR

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 crossconduction (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 5V 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.
