Texas Instruments Inc. has developed a temperature sensor that eliminates the need for individual processor resistance calibration commonly associated with remote diode monitoring. The TMP411 features programmable series resistance cancellation and diode non-ideality correction that offers easy thermal diode monitoring.

The +/-1?C remote junction and local temperature sensor offers programmable over- and under-temperature thresholds and alert pins that can be used for immediate response to potentially dangerous thermal environments. This prevents system damage and enables 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, said TI.

The TMP411 operates on a standard I?C/SMBus compatible, two-wire interface and offers 9- to 12bit resolution over a temperature range of -40?C to 125?C, with a remote temperature range of up to 150?C. For reduced power consumption, the TMP411 can be put into sleep mode, reducing current consumption to 10?A.

The TMP411 provides thermal system management for a wide range of applications, including industrial controllers, servers, PCs and laptops, and medical equipment. Other applications include central office telecom equipment, LCD/DLP/LCOS projectors, storage area networks and processor/FPGA temperature monitoring.

The TMP411 is available now and priced at Rs.73.97 ($1.75) each in quantities of 1,000. SO-8 packaging will be available in the second quarter of 2007.
