HT32 BLDC Motor Control Applications

BLDC MCUs with integrated intellengent gate-driver and driver

Under the global energy saving and carbon reduction requirements, the use of BLDC motor design for motor products has become a market trend. Its advantages are small size, high efficiency, low noise, long service life, high power density, etc., but the disadvantages lie in higher cost and high complexity of design techniques. Holtek has released a series of Arm® Cortex®-M0+ core BLDC microcontrollers, which support Hall sensor or sensorless FOC controls. For BLDC motor loads with different voltages and power, BLDC SoC MCUs with integrated intellegent gate-driver and driver are also introduced, which effectively reduces the hardware volume and the complexity of the PCB design. In addition, Holtek also provides a Workshop for motor parameter adjustment and software secondary development, assisting customers to rotate motor smoothly in a short period of time, and to mass-produce the finished BLDC prducts and introduce them into the market in time. With the IEC/UL 60730-1 software certification, the HT32F65xxx series can be widely used in applications such as the fast-growing industrial controls, household applicances, ceiling fans, range hoods, gargen tools, robots, electric scooters, quadcopters, etc.

HT32 High Accuracy Measurement Applications

24-bit Delta Sigma ADC for high accuracy measurements

HOLTEK-MCU-Series-HT32-Arm-Cortex-M (22)

Holtek has released its new Arm® Cortex®-M0+ MCUs, the HT32F59xxx series, which are specially designed for high accuracy measurement applications. The integrated A/D converter has an Effective Number of Bits (ENOB) of up to 20.7 and has a conversion rate of up to 1.6 kHz, which combined with the 12-bit SAR A/D converter that has a conversion rate of 1 MHz, allows users to implement fast and accurate measurements. Other resources include an LCD display driver, USB, UART and other commonly used serial transmission interfaces. These make the devices suitable for a diversified range of applications including electronic scales, blood pressure meters, temperature meters, high accuracy industrial controls or instrumentation etc.

HOLTEK-MCU-Series-HT32-Arm-Cortex-M (24)

Smart phones have led to the widespread popularity of Bluetooth devices. Audio transmission is a larger application of Bluetooth peripherals, following are data transmission (e.g., wearable devices or healthcare) and location services (e.g., indoor guidance or dissemination of point-of-interest information). For the latter two applications, Holtek has released a Bluetooth low energy Arm® Cortex®-M0+ dual-core SoC MCU, the HT32F67741, which has passed the BLE5.2 BQB (Bluetooth Qualification Body) certification. The device is suitable for use in health care products, home appliances, beacons, intelligent leisure products, data loggers, human interface devices (HID) service, etc.
