Description
TC650/TC651 Tiny Integrated Temperature Sensor & Brushless DC Fan Controller with Over-Temperature Alert .
The TC650/TC651 are integrated temperature sensors and brushless DC fan speed controllers.
Features
* Integrated Temperature Sensing and Multi-speed Fan Control
* Built-in Over Temperature Alert (TOVER)
* Temperature Proportional Fan Speed Control for Acoustic Noise Reduction and Longer Fan Life
* Pulse Width Modulation Output Drive for Cost and Power Savings
Applications
* in modern electronic equipment. 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/TC65
