MAX6684ESA+T

Thermal Management Overview

The MAX6684ESA+T is a fan-failure detector with an integrated power switch, designed for critical systems requiring simple on/off control. It detects excessive underspeed or locked rotors by evaluating current fluctuations at the low side of the fan, eliminating the need for tachometer signals. The device operates within a supply voltage range of 3.0V to 5.5V and supports fans rated up to 24V and 250mA. It features an active-low open-drain FAIL output and logic-level OFF input. Operating temperature ranges from -40°C to +85°C in an 8-pin SO package.

Thermal Management Feature Summary

• Dedicated fan-failure detection without software development
• Works with ordinary 2-wire fans without tachometer output
• Integrated power switch for direct fan control
• Logic-level fan driver control via OFF input
