WT51FG24
WT51FG24是一款48V三相无感测器智慧型马达控制器，适用于风扇或泵浦等无刷直流马达应用。透过整合降压转换器(buck 和 LDO)，可直接驱动48V、54V以及高达72V的无刷直流马达。 无感测器(BEMF)技术用于简化马达系统设计、降低成本并提高可靠性。智慧型马达控制器结合弦波(SVM)和150°方波驱动能力，优化电源效率、噪音性能、启动和正向/反向风车条件(顺风/逆风启转条件)。 I2C介面搭配具有读出保护功能的嵌入式记忆体，可完成马达系统和主机设备间的智慧风扇应用。内建可配置驱动电流(ISET)的NN型闸极驱动器可以完美匹配外部MOSFET并减少外部系统元件的使用。 WT51FG24采用QFN24 4 x 4 green package，适用于小型无刷直流马达系统之设计需求。
