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.
