National Semiconductor Expands Family of Precision Temperature Sensors with Patent-Pending TruTherm Technology

National Semiconductor Corporation (NYSE: NSM) today introduced a family of high-precision, remote-diode temperature sensors that employ National’s TruTherm™ thermal management technology with transistor-mode beta compensation. These new sensors are specifically designed for applications such as notebook and desktop computers and servers that are powered by high-performance microprocessors manufactured on 65 and 90 nm processes.

TruTherm Technology with Transistor-Mode Beta Compensation Provides Pinpoint-Accurate Temperature Readings for Microprocessors Developed on 65 nm, 90 nm Processes

National pioneered beta compensation technology and was the first to bring it to market, with the introduction of TruTherm technology in the spring of 2005.

TruTherm technology solves the problem of inaccurate remote temperature readings caused by variations in the internal diodes in deep sub-micron microprocessors, microcontrollers, application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs). Inaccurate remote temperature readings can lead to higher acoustic noise and reduced system performance. National’s TruTherm thermal management products improve the accuracy of temperature readings, allowing designers to achieve higher performance and efficiency in their applications, while lowering cooling-fan speed, reducing acoustic noise and extending system life.
