The TMP411 is a remote temperature sensor monitor with
a built-in local temperature sensor. The remote
temperature sensor diode-connected transistors are
typically low-cost, NPN- or PNP-type transistors or diodes
that are an integral part of microcontrollers,
microprocessors, or FPGAs.
Remote accuracy is ±1°C for multiple IC manufacturers,
with no calibration needed. The Two-Wire serial interface
accepts SMBus write byte, read byte, send byte, and
D MINIMUM AND MAXIMUM TEMPERATURE
MONITORS
receive byte commands to program the alarm thresholds
and to read temperature data.
D MULTIPLE INTERFACE ADDRESSES
D ALERT/THERM2 PIN CONFIGURATION
D DIODE FAULT DETECTION
Features that are included in the TMP411 are: series
resistance cancellation, programmable non-ideality factor,
programmable resolution, programmable threshold limits,
minimum and maximum temperature monitors, wide
