TC650  
TC651  
Tiny Integrated Temperature Sensor and Brushless DC Fan  
Controller with Over Temperature Alert  
GENERAL DESCRIPTION  
FEATURES  
The TC650/651 are integrated temperature sensors  
and brushless DC fan speed controllers. The TC650/651  
measure their junction temperature and control the speed of  
the fan based on that temperature, making them especially  
suited for applications in modern electronic equipment.  
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 TC650/651 also include a  
single trip point over temperature alert (Tover) that elimi-  
nates the need for additional temperature sensors. In addi-  
tion, the TC651 features an auto fan shutdown function for  
additional power savings.
