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.

FEATURES

■ 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

APPLICATIONS

■ CPU Thermal Management

■ System Over-or Under-Temperature Shutdown

■ Advanced Thermal Warning

■ Fan Speed Control Circuits

■ Accurate Appliance Temperature Sensing

■ Environmental Control
