TC652  
TC653  
Integrated Temperature Sensor and Brushless DC Fan  
Controller with Fan Fault Detect* and Over Temperature Alert  
GENERAL DESCRIPTION  
FEATURES  
The TC652/653 are integrated temperature sensors  
and brushless DC fan speed controllers with FanSense™  
technology. The TC652/653 measure their junction tem-  
perature and control the speed of the fan based on that  
temperature, making them especially suited for applications  
in modern electronic equipment. The FanSense™ fan fault  
detect circuitry eliminates the need for a more expensive  
3 wire fan.

Temperature Proportional Fan Speed Control for

Pulse Width Modulation Output Drive for Cost  
and Power Savings  
I
Temperature data is converted from the on-chip ther-  
mal sensing element and translated into a fractional fan  
speed from 40% to 100%. A temperature selection guide in  
the data sheet is used to choose the low and high tempera-  
ture limits to control the fan. The TC652/653 also include a  
single trip point over temperature alert (Tover) that elimi-  
nates the need for additional temperature sensors. In addi-  
tion, the TC653 includes an auto fan shutdown function for  
additional power savings.  
The TC652/653 are easy to use, require no software  
overhead, and are, therefore, the ideal choice for imple-  
menting thermal management in a variety of systems.
