Overview
The STSPIN32F0 is a System-In-Package (SiP) designed by STMicroelectronics, providing an integrated solution for driving three-phase Brushless DC (BLDC) motors. This device combines a 32-bit ARM® Cortex®-M0 core microcontroller (STM32F031C6) with a triple half-bridge gate driver, making it suitable for various driving modes. The integrated MCU enables advanced driving algorithms such as field-oriented control and 6-step sensorless control. The device also includes internal DC/DC and LDO regulators, operational amplifiers for signal conditioning, and a comparator for overcurrent protection. It is designed to operate over an extended temperature range from -40 to +125 °C and supports low power consumption in standby mode.
