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 $674 million.  Growing at an aggressive average annual growth rate of 20 percent each year, this market may reach nearly $2 billion in the next five years.  In Databeans new study, “2006 Temperature Sensors” this market is examined.  The report provides detailed coverage on application consumption, regional demand, and market share for the top temperature sensor suppliers.

Other significant findings include:

• Worldwide sensor average annual revenue growth exceeds 18 percent
• Temperature sensor revenue growth leads all other sensor categories
• Automotive and communications markets drive demand, while volumes are maintained in the computer space
• Market leaders include Analog Devices, Maxim Integrated Products and National Semiconductor
