Melexis MLX90411LZE-BAS-043-RE

The L-grade version of the MLX90411 operates over a supply voltage range from 3.2 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 on a 5 V regulated supply, or directly on the 12 V boardnet, or even the 24V boardnet for trucks. With current limit options from 330 mA up to 800 mA the MLX90411 can drive automotive applications from 0.1W up to 7W in a safe and cost-effective way, without risk for overheating the device or the motor coil. 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.
