Logic Output Temperature Sensor Family Product Information The TC07/620/621/622/623/624/ and 6501/ 6502/6503/6504 are logic output temperature sensors. Microchip's logic output temperature sensor family offers excellent temperature accuracy (1C typical) with a very low operating current of less than 600A. These devices can replace mechanical switches in a variety of sensing and control applications. The output is driven active when the temperature crosses the temperature trip point. A built-in hysteresis prevents output chattering at the temperature threshold level. Various devices operate over a power supply range of 2.7V to 18V and are usable over a wide temperature range (-40C to +125C or -55C to +125C). A variety of features provided on select devices address a broad applications spectrum: programmable hysteresis, remote temperature sensing, dual temperature limit output, externally set trip points, and TO-220 packaging for heat sink temperature measurement. High accuracy, low operating current, competitive features and ease of use make these devices the ideal choice for protecting electronic components that can be damaged by exposure to high or low temperatures. Examples of heatsensitive applications are projectors, laptops, PCs, servers, networking equipment, printers, power supplies, UPS, amplifiers, motors, and set-top boxes. Other applications include temperature alarms, simple fan control, temperature regulation, fire/heat detection, industrial heating and cooling.
