HT32 BLDC Motor Control Applications
BLDC Motor MCUs with Integrated Intelligent Gate-Driver and Driver
Under the global requirements of energy saving and carbon reduction, it has become a market trend for motor products to adopt BLDC motor design. This has advantages of small size, high efficiency, low noise, long service life, high power density, etc. However, the disadvantages lie in higher cost and high complexity of design technology. Holtek has released a series of Arm® Cortex®-M0+ core BLDC microcontrollers, inheriting the advantages of HT32 standard UL and libraries to achieve common maintenance. For BLDC motor loads with different voltages and powers, a series of BLDC motor SoC microcontrollers with integrated gate-driver and driver is also released, with a complete integration of all peripherals required for BLDC motor control. This effectively reduces the hardware size and PCB design complexity, thereby reducing the hardware and software design difficulty of BLDC motor driving systems.
