Applications
General Description
The TC652/TC653 are integrated temperature sensors
and brushless DC fan speed controllers with
FanSense ? 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.
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 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 OVER ) 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
