Device Overview

Summary

The TC650/651 are integrated temperature sensors and brushless DC fan speed controllers. The TC650/651 measure their junction temperature and control the speed of the fan based on that temperature, making them especially suited for 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 TC650/651 also include a single trip point over temperature alert (Tover) that eliminates the need for additional temperature sensors. In addition, the TC651 features an auto fan shutdown function for additional power savings. The TC650/651 are easy to use, and require no software overhead, and are therefore the ideal choice for implementing thermal management in a variety of systems.
