Texas Instruments Incorporated (TI) (NYSE: TXN) announced an integrated +/-1C maximum remote junction temperature sensor and local temperature sensor, designed to monitor thermal diodes found in CPUs, microprocessors, graphics processing units and FPGAs. Unlike other devices, the TMP411 features programmable series resistance cancellation and diode non-ideality correction which simplify and remove the time-consuming process of individual processor resistance calibration commonly associated with remote diode monitoring.
The TMP411 provides thermal system management for a wide range of applications such as industrial controllers, servers, desktop and notebook computers, and medical equipment. Additional applications include central office telecom equipment, LCD/DLPTM/LCOS projectors, storage area networks and processor/FPGA temperature monitoring.
The TMP411 has programmable over- and under-temperature thresholds and alert pins that can be used for immediate response to potentially dangerous thermal environments – preventing system damage and enabling systems to run continuously with minimal interruption. Programmable non-ideality factor correction can be used for any diode non-ideality factor associated with any processor.
The TMP411 operates on a standard I2C/SMBus compatible, two-wire interface and offers 9- to 12-bit resolution over a temperature range of -40C to 125C, with a remote temperature range of up to 150C. For reduced power consumption, the TMP411 can be put into sleep mode reducing current consumption to 10uA.
The TMP411 is available now from TI and its authorized distributors in a small MSOP-8 package. It is priced at $1.75 each in 1,000-piece quantities (suggested resale pricing). SO-8 packaging will be available in 2Q07.
TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, an online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.
