Product description
The MLX90412KLW is a low-noise all-in-one single-coil fan and pump driver IC, with a driving capability of 2.2 A, suited for air pump, water pump, axial fans, radial blower and cross blower applications.
Operating on a voltage ranging from 3.5 V to 32 V, and robust up to 40 V, the MLX90412 is well suited for use in equipment on 5 V, 12 V and 24 V power supplies, as well as portable applications with up to eight Li-ion cells (~28.8 V).
The MLX90412KLW (IT/Appliances/Industrial) is optimized for fans and pumps up to 35W such as drain pumps for washing/dryer machines and dishwashers, cross blowers in air conditioning units and ovens, desk fans and pedestal fans; and up to 45W Li-ion based applications up including robot cleaners and robot lawn mowers.
The MLX90412LLW/GLW (Automotive) can be found here.
The MLX90412 features several commutation control options, optimised for either lowest acoustic noise and vibration (sinewave), or highest efficiency and highest torque (Flat or 1/16). The patented adaptive control algorithm ensures optimal operation with the lowest reverse current, over the full speed range independent of the motor inductance or applied lead angle.
Both open loop and closed loop speed control is possible, with a wide range of dynamic (PI) settings.
