Sold and recycled (Melexis) MLX90287KZC-AA-000-RE 12V PWM single-coil fan driver for automotive applications.

summarize

The MLX90287KZC-AA-000-RE is a fully integrated, rugged and high-performance Hall Efficate-based fan driver IC for energy efficient cooling fan design that allows cooling fan speed to be controlled via PWM or analog signals. The device will be of great benefit to information technology devices such as desktop computers, game consoles, and cooling fans for automotive applications such as LED headlights.

The MLX90287 uses a single-chip solution to drive a low-noise, adjustable-speed single-coil brushless cooling fan. The MLX90287 has an operating supply voltage range of 4.5V to 18V, and its target application is the widely used "12 V" cooling fan application. With the integrated power stage, the MLX90287 can easily drive cooling fans rated up to 550 mA (continuous), thus meeting the requirements of most applications. The device has an operating temperature range of -40 to 150°C, making it suitable for use in a variety of harsh environments such as automotive, industrial and aerospace.
