MAX31740  
Ultra-Simple Fan-Speed Controller  
General Description  
Features  
The MAX31740 is a sophisticated, yet easy-to-use fan-  
speed controller. It monitors the temperature of an external  
NTC thermistor and generates a PWM signal that can be  
used to control the speed of a 2, 3, or 4-wire fan. The fan  
control characteristics are set using external resistors,  
thereby eliminating the need for an external microcon-  
troller. Controllable characteristics include the starting  
temperature for fan control, PWM frequency, fan speed  
at low temperatures, and slope of the temperature-duty-  
cycle transfer function.

Because the operating characteristics are selected by  
hardwired passive components, a simple, low-cost fan-  
speed controller can be implemented without the need  
for firmware development. This can dramatically reduce  
development time for the fan control function.
