[原创] TIF2806x系列三相BLDC马达控制参考设计

TI公司的F2806x Piccolo系列MCU包括C28x内核和高度集成控制外设CLA,具有高效32位CPU,工作频率90MHz,16x16和32x32乘法累加器(MAC),哈佛总线架构,嵌入存储器包括多达256KB闪存,100KB RAM,2KB OTP ROM,6路DMA,3.3V工作,主要用在开关电源(SMPS),智能电网和动力线通信,太阳能逆变器和转换器,AC/DC转换器等.本文介绍了F2806x系列主要特性,框图和相关框图,三相无刷/PMSM低电流马达控制解决方案主要特性,电路图和材料清单.

The F2806x Piccolo family of microcontrollers (MCUs) provides the power of the C28x core and CLA coupled with highly integrated control peripherals in low pin-count devices. This family is code-compatible with previous C28x-based code, and also provides a high level of analog integration.

An internal voltage regulator allows for single-rail operation. Enhancements have been made to the High-Resolution Pulse Width Modulator (HRPWM) module to allow for dual-edge control (frequency modulation). Analog comparators with internal 10-bit references have been added and can be routed directly to control the ePWM outputs. The ADC converts from 0 to 3.3-V fixed full-scale range and supports ratio-metric VREFHI/VREFLO references. The ADC interface has been optimized for low overhead and latency.
