General Description
The TC650/TC651 are integrated temperature sensors
and brushless DC fan speed controllers. The TC650/
TC651 measure the 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
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
TC650/TC651 also include a single trip point over-
temperature alert (T
OVER
) that eliminates the need for
additional temperature sensors. In addition, the TC651
features an auto fan shutdown function for additional
power savings.
The TC650/TC651 are easy to use, require no software
overhead and are, therefore, the ideal choice for
implementing thermal management in a variety of
systems.
