MLX90412-L SINGLE-COILFAN & PUMP DRIVER:LOW NOISE FAN & PUMP DRIVER FOR AUTOMOTIVE APPLICATIONS

PublishTime：2022-06-29

●The L-grade version of the MLX90412 operates over a supply voltage range from 3.5 V to 32 V,and is robust up to 40 V.With an operating temperature up to 150°C,it is a perfect fit for any automotive fan, blower or pump application directly on the 12 V boardnet, or even the 24 V boardnet for trucks.With current limit options from 1.5 A up to 2.2 A,the MLX90412 drives automotive applications up to 20 W in a safe and cost effective way,without risk for overheating the device or the motor coil,in complement to the MLX90411 which covers applications up to 7W.The closed-loop speed control limits the speed variation to less than +/-5% regardless of the load condition,battery voltage variation,or fan production tolerances over the full temperature range.Together with the adaptive low noise commutation it enables industry standard efficiency and acoustic performance.Multiple commutation options are available,including a sinewave option offering unprecedented low levels of vibration.
