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 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 4 5 6 VCC LOW LIMIT HIGH LIMIT CONTROL APPLICATIONS
