Original Press Release:
National Semiconductor's New Thermal Management Sensor Provides Highest Accuracy for Extended Temperature Environments
Industry's Highest-Performance Digital Temperature Sensor Delivers ± 1 Degree C Accuracy from 130 Degrees C to 160 Degrees C in Automotive Applications
SANTA CLARA, Calif. - October 16, 2008 - National Semiconductor Corp. (NYSE:NSM) today introduced a digital temperature sensor that monitors automotive system temperature up to 175 degrees C and delivers ± 1 degree C accuracy between 130 degrees C and 160 degrees C. The device is manufactured on an automotive grade flow meeting AEC-Q100 Grade 0 qualification requirements. National will demonstrate this product at the Convergence 2008 Conference in Detroit, Michigan, from Oct. 20-22 at Booth 1319.
The LM95172Q's pinpoint accuracy at high temperatures permits lower system guard bands. System engineers now can develop a reliable electronic control unit (ECU) that consistently runs at higher temperatures, allowing for optimal oil viscosity, smaller system form factor and lower weight. These elements enable increased fuel efficiency.
Key Features - LM95172Q Digital Temperature Sensor The LM95172Q is the industry's first integrated 175 degrees C digital-output temperature sensor with a serial peripheral interface (SPI) and MICROWIRE® bus interface. The LM95172Q is a member of National's PowerWise® family of products that enable customers to develop more energy-efficient products.
The LM95172Q is supplied in die form for mounting on hybrid circuit boards and offers temperature monitoring between -40 degrees C and 175 degrees C. The LM95172Q features a 16-bit sigma-delta analog-to-digital converter (ADC), fast conversion rate of 35 ms and high resolution of 0.008 degrees C/LSB. The device also includes a temperature switch as well as self diagnosis to ensure safe, continuous operation.
National's automotive portfolio includes temperature sensors, data converters, audio and operational amplifiers, and power management and interface circuits. These energy-efficient products help electronic system designers reduce space, lower operating temperatures and conserve on overall power consumption.
Pricing and Availability
Pricing for the LM95172Q is $1.25 each in 1,000-unit quantities. The device is sampling now with production volumes available in the fourth quarter of 2008. For more information, or to order samples and an evaluation board, visit national.com/pf/LM/LM95172Q.html.
