Description
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.
