Overview
The STSPIN32F0252, produced by STMicroelectronics, is a highly integrated system-in-package designed for driving three-phase applications. It combines an STM32F031x6x7 microcontroller (MCU) featuring an ARM® 32-bit Cortex®-M0 CPU with a 250V triple half-bridge gate driver. This integration enables the device to drive N-channel power MOSFETs or IGBTs, making it suitable for a wide range of high-voltage applications. The device includes advanced protection features such as a comparator with smartSD function for fast overcurrent protection, high-voltage bootstrap diodes, and UVLO, interlocking, and deadtime functions to ensure safe and efficient operation.
