Temp Sensor Digital 8-Pin MSOP T/R

The TC650 is 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. Temperature data is converted from the on-chip thermal sensing element and translated into a fractional fan speed from 40% to 100%. The TC650 also include a single trip point overtemperature 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 are easy to use, require no software overhead and are, therefore, the ideal choice for implementing thermal management in a variety of systems.
