These system monitors have the capability of measuring remote • n-FACTOR CORRECTION temperatures, on-chip temperatures, and system • TEMPERATURE ALERT FUNCTION voltage/power/current consumption. • AVERAGING The remote temperature sensor diode-connected • 12-BIT RESOLUTION transistors are typically low-cost, NPN- or PNP-type • DIODE FAULT DETECTION transistors or diodes that are an integral part of microcontrollers, microprocessors, or FPGAs. • SENSES BUS VOLTAGES FROM 0V TO +26V Remote accuracy is ±1°C for multiple IC • REPORTS CURRENT IN AMPS, VOLTAGE IN manufacturers, with no calibration needed. The VOLTS AND POWER IN WATTS two-wire serial interface accepts SMBus ™ or • HIGH ACCURACY: 1% MAX OVER TEMP two-wire write and read commands. • WATCHDOG LIMITS: The onboard current shunt monitor is a high-side – Upper Over-Limit current shunt and power monitor. It monitors both the shunt drop and supply voltage. A programmable – Lower Under-Limit calibration value (along with the TMP512/TMP513 internal digital multiplier) enables direct readout in APPLICATIONS amps; an additional multiplication calculates power in • DESKTOP AND NOTEBOOK COMPUTERS watts. The TMP512 and TMP513 both feature two separate onboard watchdog capabilities: an over-limit • SERVERS comparator and a lower-limit comparator. • INDUSTRIAL CONTROLLERS These devices use a single +3V to +26V supply, • CENTRAL OFFICE TELECOM EQUIPMENT drawing a maximum of 1.4mA of supply current, and • LCD/ DLP®/LCOS PROJECTORS they are specified for operation from –40°C to • STORAGE AREA NETWORKS (SAN) +125 °C. 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.
