MAX6650EUB Description

Short technical summary and product information.

The MAX6650EUB is an integrated circuit designed for regulating and monitoring the speed of brushless DC fans. It utilizes an SMBus/I2C-compatible interface for communication, allowing for precise control over fan speeds. This device is capable of operating with 5VDC and 12VDC fans, automatically adjusting the fan's tachometer frequency to a programmed value.

 

Key electrical specifications include a supply voltage range of 3V to 5.5V and a typical operating current of 10mA. The operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions. The MAX6650EUB supports unipolar motor types and is configured as a pre-driver for low-side applications.

 

This fan controller is available in a compact 10-pin uMAX package, designed for surface mount applications. Its functionality extends to applications such as RAID systems, servers, workstations, desktop computers, networking equipment, and telecommunications devices, where efficient thermal management is critical.
