# SINGLE COIL EXHAUST FAN

## Description

The MLX90412-K operates over a supply voltage range from 3.5 V to 32 V, and is robust up to 40 V, With a current limit up to 2.2A, the MLX90412 can drive applications up to 35 W in a safe way without risk of overheating the device or the motor coil. The closed-loop speed control and adaptive low noise commutation enable industry-standard efficiency with lowest acoustic noise.
