TC623 Datasheet PDF - TelCom Semiconductor Inc => Microchip

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
