The STSPIN32F025x system-in-package is an extremely integrated solution for driving three-phase applications, helping designers to reduce PCB area and overall bill-of-material.
It embeds an STM32F031x6x7 featuring an ARM® 32-bit Cortex®-M0 CPU and a 250 V triple half-bridge gate driver, able to drive N-channel power MOSFETs or IGBTs.
A comparator featuring advanced 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.
