TC650/TC651 Data Sheet Docket ↓TC650/TC651 Tiny Integrated Temperature Sensor & Brushless DC Fan Controller with Overtemperature Alert Features General Description Integrated Temperature Sensing and Multi-speed Fan Control Built-in Overtemperature Alert (TOVER) Temperature-proportional Fan Speed Control for Acoustic Noise Reduction and Longer Fan Life Pulse Width Modulation (PWM) Output Drive for Cost and Power Savings Solid-state Temperature Sensing В±1п‚°C (typ.) Accuracy from 25п‚°C to +70п‚°C Operating Range: 2.8V – 5.5V TC651 includes Automatic Fan Shutdown Low Operating Current: 50 ВµA (typ.) 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. Applications Thermal Protection For Personal Computers Digital Set-Top Boxes Notebook Computers Data Communications Power Supplies Projectors Related Literature Application Note 771 (DS00771) 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 overtemperature alert (TOVER) that eliminates the need for additional temperature sensors. In addition, the TC651 ...
