    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 ±1C (typ.) Accuracy from 25C to +70C Operating Range: 2.8V – 5.5V TC651 includes Automatic Fan Shutdown Low Operating Current: 50 µA (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

    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 ...
