MAX6651EEE Description

Short technical summary and product information.

The MAX6651EEE is an integrated circuit designed for controlling and monitoring the speed of 5VDC/12VDC brushless fans. It utilizes an SMBus/I2C-compatible interface to automatically adjust fan speed by regulating the voltage across the fan using an external transistor. This device can monitor up to four fans in parallel, controlling them as a single unit.

 

Key features include closed/open-loop fan-speed control, a programmable alert output, and general-purpose input/output (GPIO) pins for additional hardware control. The MAX6651EEE supports a supply voltage range of 3V to 5.5V and operates within a temperature range of -40°C to 85°C.

 

Designed for applications such as servers, workstations, and telecommunications equipment, the MAX6651EEE comes in a compact 16-pin QSOP package, suitable for surface mount applications. Its functionality includes hardware full-on override and synchronization capabilities for multiple devices.

 

This fan controller is well-suited for systems requiring precise thermal management and fan speed control, ensuring optimal performance and reliability.
