ST STSPIN32F0A三相BLDC马达驱动方案
ST公司的STSPIN32F0A是SIP三相BLDC马达驱动器,嵌入了三个可驱动功率MOSFET的半桥栅极驱动器,驱动电流600mA,时钟频率高达48MHz的32位ARM® Cortex®-M0核,4KB SRAM和32KB闪存,工作电压6.7V-45V,内部的DC/DC转换器提供3.3V用来给MCU和外部元件供电,而LDO线性稳压器用来给栅极驱动器供电,主要用在智能制造设备,电动工具,FAN和泵,家用电器如真空吸尘器,电吹风机,空气净化器和咖啡机,以及高技术应用如无人机,教育/家庭机器人,平衡环.本文介绍了STSPIN32F0A主要特性,框图和模拟IC框图,应用案例电路图以及评估板STEVAL-SPIN3202主要特性,元件分布图,电路图和材料清单.
The STSPIN32F0A is a System-In-Package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes. It embeds a triple half-bridge gate driver able to drive power MOSFETs with a current capability of 600 mA (sink and source). The high- and low-side switches of same half-bridge cannot be simultaneously driven high thanks to an integrated interlocking function.
An internal DC/DC buck converter provides the 3.3 V voltage suitable to supply both the MCU and external components. An internal LDO linear regulator provides the supply voltage for gate drivers.
