Fan-Failure Detector with Integrated  
Power Switch  
General Description  
Features  
The MAX6684 is an integrated fan-failure detector that  
detects when a fan exhibits excessive underspeed or a  
locked rotor. This device is especially well suited for criti-  
cal systems where no fan control, or simple on/off control  
is desired. The MAX6684 detects fan failure by evaluat-  
ing fluctuations in current at the low side of the fan; no  
tachometer signal is necessary. The output of the device,  
FAIL, is an active-low, open-drain alarm. The MAX6684  
can also be used to switch the fan on or off, based on  
the state of a logic-level input, OFF. This device can be  
used with fans rated at up to 24V and 250mA. The  
MAX6684 is available in an 8-pin SO package, and is  
specified for operation from -40°C to +85°C.
