Description
TC652/TC653 Integrated Temperature Sensor & Brushless DC Fan Controller with FanSense™ Detect & Over-Temperature .
The TC652/TC653 are integrated temperature sensors and brushless DC fan speed controllers with FanSense™ technology.
Features
* Integrated Temperature Sensing and Multi-speed Fan Control
* FanSense™ Fan Fault Detect Circuitry
* Built-in Over-Temperature Alert (TOVER)
* Temperature Proportional Fan Speed Control for Acoustic Noise Reduction and Longer Fan Life
* Pulse Width Modulation
Applications
* in modern electronic equipment. The FanSense™ Fan Fault detect circuitry eliminates the need for a more expensive 3-wire fan. Temperature data is converted from the on-chip thermal sensing element and translated into a fractional fan speed from 40% to 100%. A temperature selection guide in the data
