STSPIN32G0251Q

STSPIN32G0251Q is a 250V three-phase BLDC controller with an embedded MCU. It is a system-in-package providing an integrated solution suitable for driving three-phase applications. It embeds an MCU featuring an Arm 32bit Cortex®-M0+ CPU and a 250V 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. It is used in applications such as three-phase motor drivers, inverters, industrial appliances, and fans.
