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.
