Applications

CPU Thermal Management System Over or Under Temperature Shutdown Advanced Thermal Warning Fan Speed Control Circuits Accurate Appliance Temperature Sensing Environmental Control

The a 3V solid-state, programmable temperature sensor designed for use in thermal management applications. It features dual thermal interrupt outputs (LOW LIMIT and HIGH LIMIT) each of which are set with an external resistor. The HIGH LIMIT and LOW LIMIT outputs are driven active (high) when measured temperature equals the user programmed limits. The CONTROL output is driven active (high) when temperature equals the HIGH LIMIT set point and turned off when temperature falls below the LOW LIMIT set point. The CONTROL output can be used to provide simple ON/OFF control to a cooling fan if so desired. Low voltage operation, easy set point programming, small size and low cost make the TC623 an ideal choice for many thermal management applications.
