STMicroelectronics' STSPIN32F060x system-in-package is an extremely integrated solution for driving three-phase applications, helping designers to reduce printed circuit board (PCB) area and overall bill of materials (BOM). It embeds an STM32F031x6x7 featuring an Arm 32-bit Cortex-M0 CPU and a 600 V triple half-bridge gate driver, able to drive N-channel power MOSFETs or IGBTs. A comparator featuring advanced smart shutdown (smartSD) function is integrated, ensuring fast and effective protection against overload and overcurrent. The high-voltage bootstrap diodes are also integrated, as well as anti-cross-conduction, 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 algorithms, including the speed control loop.
