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 ±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
Digital Set-Top Boxes

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 ...
