RT7079是針對三相PMSM/BLDC電機應用的二合一控制器，其中含有三相電機控制器、三相門極驅動器、三隻自舉二極體、5V輸出的線性穩壓器和一個Buck轉換器。<BR>RT7079內含32位ARM Cortex™-M0 MCU和完成無感測器場向量定向控制所需要的各種週邊電路，包含ADC、DAC、通訊介面、SVPWM生成器、看門狗計時器、電流檢測器和欠壓鎖定保護、短路保護、堵轉保護等功能，由其構成的系統元件數量少，PCB尺寸和系統成本都得以降低。<BR>RT7079使用內建自舉網路可驅動三組半橋配置的外部N-MOSFET開關，工作電壓可達58V，具有內建的死區時間可避免外接的MOSFET發生直通短路狀況。<BR>RT7079的封裝形式為WQFN-48L 7x7。
