SBOS425A – DECEMBER 2008 – REVISED MARCH 2009 ±1°C TEMPERATURE SENSOR with Automatic Beta Compensation, Series-R, and η-Factor in a SOT23-8 234 • SOT23-8 PACKAGE The TMP441 and TMP442 are remote temperature monitors with a built-in local temperature sensor. • ±1°C REMOTE DIODE SENSOR (MAX) Remote temperature sensor diode-connected • ±1°C LOCAL TEMPERATURE SENSOR (MAX) transistors are typically low-cost, NPN- or PNP-type • AUTOMATIC BETA COMPENSATION transistors or diodes that are an integral part of • SERIES RESISTANCE CANCELLATION microcontrollers, microprocessors, or field-programmable gate arrays (FPGAs). • η-FACTOR CORRECTION Remote accuracy is ±1°C for multiple IC • TWO-WIRE/SMBus™ SERIAL INTERFACE manufacturers, with no calibration needed. The • MULTIPLE INTERFACE ADDRESSES Two-Wire serial interface accepts SMBus write byte, • DIODE FAULT DETECTION read byte, send byte, and receive byte commands to • RoHS-COMPLIANT AND NO Sb/Br configure the device. • TRANSISTOR AND DIODE MODEL The TMP441 has a single remote temperature OPERATION monitor with address pins. The TMP442 has dual remote temperature monitors, and is available with two different interface addresses. All versions include automatic beta compensation (correction), series • PROCESSOR/FPGA TEMPERATURE resistance cancellation, programmable non-ideality MONITORING factor ( η-factor), wide remote temperature • LCD/DLP®/LCOS PROJECTORS measurement range (up to +150°C), and diode fault • SERVERS detection. • CENTRAL OFFICE TELECOM EQUIPMENT The TMP441 and TMP442 are both available in an • STORAGE AREA NETWORKS (SAN) 8-lead, SOT23 package. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 DLP is a registered trademark of Texas Instruments. 3 SMBus is a trademark of Intel Corporation. 4 All other trademarks are the property of their respective owners.
