Microchip TC652AEVUA

Hot25°C，45°C±2.5°C

Overview

The TC652/653 are integrated temperature sensors and brushless DC fan speed controllers with FanSense™ technology. The TC652/653 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. The FanSense™ fan fault detect circuitry eliminates the need for a more expensive 3 wire fan.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 TC652/653 also include a single trip point over temperature alert (Tover) that eliminates the need for additional temperature sensors. In addition the TC653 includes an auto fan shutdown function for additional power savings.The TC652/653 are easy to use, require no software overhead, and are therefore the ideal choice for implementing thermal management in a variety of systems.FanSense™ is a trademark of Microchip Technology Inc.
