General Description

• TC651 includes Auto Fan Shutdown

• Low Operating Current: 50µA (Typical)

The TC650/TC651 are integrated temperature sensors

and brushless DC fan speed controllers. The TC650/

TC651 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.

Applications

• Thermal Protection For Personal Computers

• Digital Set-Top Boxes

• Notebook Computers

• Data Communications

• Power Supplies

Temperature data is converted from the on-chip

thermal sensing element and translated into

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

additional temperature sensors. In addition, the TC651

features an auto fan shutdown function for additional

power savings.

• Application Note: AN771

Device Selection Table

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.
