TC650/TC651

Tiny Integrated Temperature Sensor & Brushless DC Fan

Controller with Overtemperature Alert

Features

General Description

• Integrated Temperature Sensing and Multi-speed

Fan Control

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.

• Built-in Overtemperature Alert (T_OVER

)

• Temperature-proportional Fan Speed Control for

Acoustic Noise Reduction and Longer Fan Life

• Pulse Width Modulation (PWM) Output Drive for

Cost and Power Savings

Temperature data is converted from the on-chip

thermal sensing element and translated into

• Solid-state Temperature Sensing

• ±1°C (typ.) Accuracy from 25°C to +70°C

• Operating Range: 2.8V – 5.5V

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.

• TC651 includes Automatic Fan Shutdown

• Low Operating Current: 50 µA (typ.)

Applications

• Thermal Protection For Personal Computers

• Digital Set-Top Boxes

• Notebook Computers

• Data Communications

• Power Supplies

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.
