GENERAL DESCRIPTION

The TC622 and TC624 are programmable solid state temperature switches designed to replace mechanical switches in sensing and control applications. Both devices integrate the temperature sensor along with a voltage reference and all required detector circuitry to form a stand-alone temperature switch. The desired temperature set point is set by the user with a single external resistor.

FEATURES

■ Temperature Set Point Easily Programs with a Single External Resistor

■ Operates with 2.7V Power Supply (TC624)

■ TO-220 Package for Direct Mounting to Heatsink (TC622xAT) or Standard 8-Pin PDIP and SOIC

■ Cost Effective

APPLICATIONS

■ Power Supply Over-temperature Detection

■ Consumer Electronics

■ Fire/ Heat Detection

■ UPSs, Amplifiers, Motors

■ CPU Thermal Management in PCs
