The STSPIN32F0 is a System-In-Package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes. It embeds a triple half-bridge gate driver able to drive power MOSFETs or IGBTs with a current capability up to 1A depending on the version. The high- and low-side switches of the same half-bridge cannot be simultaneously driven high thanks to an integrated interlocking function.
All the integrated features of STSPIN32F0x family make design of the application PCB easier, and result in reduced PCB area consumption, bill of material and overall application cost.
