STMicroelectronics-STSPIN32F0-product-picture

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 of 600 mA (sink and source). The high- and low-side switches of same half-bridge cannot be simultaneously driven high thanks to an integrated interlocking function. An internal DC/DC buck converter provides the 3.3 V voltage suitable to supply both the MCU and external components.
