MLX90287LLD-AAA-000-SP

The hummingbird’s beating wings flap at extremely high frequencies, typically around 50 times per second. This allows it to fly at speeds exceeding 15 m/s, to fly backwards or to seemingly be suspended in the air in perfect balance. What better animal to reflect the motor/control driver and actuator capacities? MLX90287 & MLX90297 SINGLE-COIL FAN DRIVERS 12V ROBUST FAN DRIVERS MLX90287 & MLX90297 The MLX90287 & MLX90297 are the 2nd GEN of all-in-one single-coil fan drivers with highly sensitive hall sensor using AGC control for optimal low noise/high efficiency commutation control regardless of the magnetic field strength. The PWM input allows controlling the fan speed in combination with a number of resistor-configurable settings to adapt the speed curve to application specific requirements. Targeting low noise fan control in VGA card cooling applications, the GEN II low noise motor control features also have been leveraged in demanding home appliance, white goods, industrial and automotive cooling systems.
