MCUs optimize BLDC motor applications
Microchip’s AVR EB family of MCUs provides complex waveform control in systems that employ brushless DC (BLDC) motors. Aimed at a wide range of cost-sensitive applications, the microcontrollers can adjust speed, timing, and waveform shape, creating sinusoidal and trapezoidal waveforms. According to the manufacturer, the devices improve the smoothness of motor operations, reduce noise, and increase efficiency.
On-chip peripherals enable multiple functions with minimal programming. The MCUs respond quickly to changes in operating conditions. and adjustments can be made on-the-fly with near-zero latency. They can also lower overall BOM cost since several tasks, such as reading environmental sensors and serial communication, can be performed independent of the CPU.
To enable smooth BLDC motor control, the MCUs employ a 16-bit timer/counter with four compare channels for pulse width modulation and waveform extension. A 24-bit timer/counter provides frequency generation and timing, while a programming and debug interface disable (PDID) function enhances code protection.
In addition to motor control, the AVR EB series can be used for predictive maintenance, home automation, industrial process control, and automotive tasks.
AVR EB MCUs are offered in various package types (some as small as 3×3 mm), with 14, 20, 28, and 32 pins. The AVR16EB32 Curiosity Nano board allows evaluation and prototyping.
