Temperature sensor IC market heats up

12 July 2006 News

Market intelligence supplier, Databeans, has just released its first market report on the market for temperature sensor ICs, titled '2006 Temperature Sensors'.

In this study, it discusses trends and emerging market opportunities for thermal management devices.

Today's electronic application designs are shrinking in size at a rate similar to the growing complexity of the devices inside. With more complex designs residing on smaller boards, temperature management becomes a real issue. The importance of thermal management is gaining momentum, providing a strong market opportunity for devices servicing this function.

Temperature measurement in electronics has been around for years. Prior to the introduction of integrated temperature sensing circuits, this function was performed by thermocouplers and RTDs (resistive temperature detectors). Both are passive devices, a market on the decline, as integrated solutions continue to reach competitive price points.

Temperature sensors have been used in many embedded applications, and of course, in the more common computer processor thermal management function. Obvious applications include power supplies, computers, peripherals, automotive, and industrial equipment. With lower power products on the market, new applications are uncovered, such as battery powered GPS instruments, and even high volume wireless handsets.

Databeans estimates the current market for temperature sensor ICs at $674m. Growing at an aggressive average annual growth rate of 20% each year, this market may reach nearly $2 bn in the next five years.

The research group also finds that temperature sensor revenue growth leads all other sensor categories. Automotive and communications markets drive demand, it says, while volumes are maintained in the computer space.
