STSPIN32G0252Q

STSPIN32G0252Q is a 250V three-phase BLDC controller with an embedded STM32 MCU. It features an Arm 32bit Cortex®-M0+ CPU and a 250 V triple half-bridge gate driver, able to drive N-channel power MOSFETs or IGBTs. A comparator featuring an advanced smartSD function is integrated into the device, ensuring fast and effective protection against overload and overcurrent. The high-voltage bootstrap diodes are also integrated, as well as anti-cross-conduction (interlocking), deadtime, and UVLO protection on both the lower and upper driving sections, which prevents the power switches from operating in low-efficiency or dangerous conditions. Matched delays between low and high-side sections guarantee no cycle distortion. The integrated MCU is based on the high-performance 32bit Arm Cortex®-M0+ core, operating at a frequency up to 64MHz and featuring a memory protection unit (MPU), which enhances the application’s security.
