Fan / Ceiling Fan

This solution uses a motor to convert electrical energy into winds. It provides three sets of complementary, dead-band PWM outputs, high-speed A/D converters, and comparators to drive DC brushless motors.

The NuMicro M051 series provides a high-performance and low-cost 32-bit Arm® Cortex®-M0 core, runs up to 50 MHz at 2.5V ~ 5.5V, -40℃ ~ 105℃, and supports 32-bit hardware multiplier with hardware divider, 64 KB Flash and 4 KB SRAM, highly integrated 12-bit ADC and high sample range 1 MSPS, three pares PWM output (include complementary and dead time) , high-precision 22 MHz oscillator to reduce system BOM cost, and rich peripheral such as I²Cx2, SPIx2, UARTx2, Anti-theft lock code bit, 96-bit Unique ID and 128-bit Unique customer ID, and strong Anti-jamming ability (ESD 8kV, EFT 4kV) . Based on the above features, the NuMicro M051TM series is a very cost-effective DC brushless motor fan solution.
