technology. The TC652/TC653 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.
The FanSense
Fan Fault detect circuitry eliminates
the need for a more expensive 3-wire fan.

fractional fan speed from 40% to 100%. A temperature
selection guide in the data sheet is used to choose the
low and high temperature limits to control the fan. The
TC652/TC653 also include a single trip point over
temperature alert (T

) that eliminates the need for
additional temperature sensors. In addition, the TC653
includes an auto fan shutdown function for additional
power savings.

The TC652/TC653 are easy to use, require no software
overhead and are therefore the ideal choice for
implementing thermal management in a variety of
systems.
