ST STSPIN32F0252带MCU 250V三相控制器解决方案

ST公司的STSPIN32F0252是系统封装芯片250V三相控制器,嵌入了ARM® 32位 Cortex®-M0 CPU和250V三相半桥栅极驱动器,能够驱动N沟功率MOSFET或IGBT.器件还集成了具有先进smartSD功能的比较器,从而保证快速和有效的对过载和过流的保护.器件还集成了高压自举二极管,以及抗交叉导通,死区和低和高驱动部分的UVLO保护,从而避免了功率开关工作在低效率或危险条件.低和高边部分的匹配延迟保证了没有周期失真.集成的ARM MCU允许进行FOC,6步无传感器和其它先进的算法,包括速度控制回路.栅极驱动电压从9V到20V, ARM® 32位 Cortex®-M0 CPU工作频率高达48MHz,工作温度-40 到 +125 C.主要用在电池供电和110Vac电源和花园工具,工业风扇和泵,家用电器以及工业和家庭自动化.本文介绍了STSPIN32F0252主要特性,框图,以及评估板STEVAL-PTOOL2V1主要特性,主要电路框图和电路图,材料清单.

 

The STSPIN32F025x system-in-package is anextremely integrated solution for driving threephaseapplications, helping designers to reducePCB area and overall bill-of-material.

It embeds an STM32F031x6x7 featuring anARM® 32-bit Cortex®-M0 CPU and a 250 V triplehalf-bridge gate driver, able to drive N-channelpower MOSFETs or IGBTs.

A comparator featuring advanced smartSDfunction is integrated, ensuring fast and effectiveprotection against overload and overcurrent.

The high-voltage bootstrap diodes are alsointegrated, as well as anti cross-conduction,

deadtime and UVLO protection on both the lowerand upper driving sections, which prevents thepower switches from operating
