ET1251是設計為PMSM / BLDC中電壓大功率馬達應用的產品，包含了三相向量無感馬達單晶片和200V N+N閘極驅動器的整合型晶片。
ET1251整合8位元8051-1T內核和閘極驅動電路，搭載祥誠FOC硬件化馬達演算控制單元，使無感傳感器馬達控制易於上手。整合各種系統級外設功能，如Tx/Rx、多通道ADC、PWM 直接讀取介面、PWM產生與OCP等介面，減
少元件數量、電路板空間和系統成本。ET1251驅動外部器件NMOSFET採用半橋配置，外部自舉式電路200V。ET1251採用LQFP-48 7x7封裝。
祥誠是隸屬於漢民集團的子公司, 在晶圓投單/封測皆與國內一線大廠合作,於2015/04通過ISO9001-2008的認證,
是一家專注於直流無刷馬達技術開發的IC設計與方案公司。
MCU僅需提供簡單暫存器指令,就能實現完整有效率的馬達控制,輕鬆簡單解決以往所有難題。
