Solution Description

Thanks to the high integration level of the STSPIN32F0A, the control board provides a powerful power stage, the analog circuitry implementing current sensing and overcurrent protection and a Cortex-M0 microcontroller performing a Field-Oriented Control with closed-loop positioning.

The ST1S14 step-down monolithic power switching and the L78L high-current 3.3 V linear regulator allow to provide the logic supply voltage with compact and safe solution.

A differential serial interface widespread in industrial environment is realized through the STR485.

The power stage with STL7DN6LF3 N-channel power MOSFET provide superior switching performance.
