DESCRIPTION

· The TC622 and TC624 are programmable solid-state temperature sensors designed to replace mechanical switches in sensing and control applications.

· Both devices integrate the temperature sensor with a voltage reference and all required detector circuitry.

· The desired temperature set point is set by the user with a single external resistor.

· Ambient temperature is sensed and compared to the programmed set point.

· The OUT and OUT outputs are driven to their active state when the measured temperature exceeds the programmed set point.

· The TC622 has a power supply voltage range of 4.5V to 18.0V while the TC624 operates over a power supply range of 2.7V to 4.5V.

· Both devices are usable over a temperature range of -40°C to +125°C.

· Both devices feature low supply current making them suitable for portable applications.

· Eight-pin through-hole and surface mount packages are available. The TC622 is also offered in a 5-pin TO-220 package.

· The TC622 and TC624 are single point temperature detectors ideal for use in a wide variety of applications.

FEATURES

· Temperature set point easily programs with a single external resistor.

· Operates with 2.7V power supply (TC624).

· TO-220 package for direct mounting to heatsink (TC622XAT) or standard 8-Pin PDIP and SOIC.

APPLICATIONS

· Power supply over-temperature detection.

· Consumer electronics.

· Fire/Heat detection.

· UPSs, Amplifiers, Motors.

· CPU thermal management in PCs.
