1 TC623 3V, DUAL TRIP POINT TEMPERATURE SENSOR FEATURES s s s s s s s Integrated Temp Sensor and Detector Operate from a Supply Voltage as Low as 2.7V Replaces Mechanical Thermostats and Switches On-Chip Temperature Sense 8-Pin DIP or SOIC for Direct PCB Mounting 2 User-Programmable Temperature Set Points 2 Independent Temperature Limit Outputs Heat/Cool Regulate Output GENERAL DESCRIPTION The TC623 is 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 program with a single 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 setpoint, and turned off when temperature falls below the LOW LIMIT setpoint. The CONTROL output can be used to provide simple ON/OFF control to a cooling fan if so desired. Low voltage operation, easy setpoint programming, small size and low cost make the TC623 an ideal choice for many thermal management applications. 2 3 APPLICATIONS s s s s s s CPU Thermal Management System Over-or Under-Temperature Shutdown Advanced Thermal Warning Fan Speed Control Circuits Accurate Appliance Temperature Sensing Environmental Control 4 ORDERING INFORMATION Part No. Package 8-Pin SOIC 8-Pin Plastic DIP 8-Pin SOIC 8-Pin Plastic DIP 8-Pin SOIC Temperature Range ……
