Nuvoton has developed a series of motor control microcontrollers with rich peripherals and control algorithms specially designed for brushless DC motors (BLDC) to increase motor operating efficiency, reduce energy consumption, ease the development effort, and to reduce manufacturing cost.

Based on years of experience in the microcontroller business, Nuvoton offers a new generation of 32-bit NuMicro® microcontrollers embedded with ARM® Cortex®-M0 core and peripherals for motor applications including: High Precision RC Oscillator, PWM, ADC, Comparator, Gate Driver, FOC (Field Oriented Control), supports wide operating voltage from 2.5V to 5.5V, industrial temperature range from -40℃ to 105℃ with high noise immunity.

The NuMicro® Motor Control microcontrollers includes the NM1800 series which embedded an up to 600V high voltage gate driver, the high performance NM1500 series with embedded CAN 2.0B, two ADCs, two OPAmps and FOC hardware; the multi-purpose NM1200 series which supports single-shunt current sampling; and the low pin count NM1100 series. The NuMicro® Motor Control microcontrollers are now under mass production and are ideal for electric vehicles, industrial control, fan drives, power tools, industrial automation, ESC, power, and motor control applications.
