MAX31740 Datasheet - Maxim Integrated

MAX31740 Ultra-Simple Fan-Speed Controller

The MAX31740 is a sophisticated, yet easy-to-use fanspeed 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 elimina.

MAX31740 Features

* Self-Contained PWM Fan Control

* No Micro Needed

* Controls Speed of 2-, 3-, or 4-Wire Fans

* Resistors Set Fan Control Characteristics

* Smooth, Linearly Varying PWM Duty Cycle Minimizes Audibility of Fan Noise

* Accurately Monitors External Thermistor Temperature
