TEMPERATURE MONITORING
DESCRIPTION
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
receive byte commands to program the alarm thresholds
and to read temperature data.
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
remote temperature measurement range (up to +150
°C),
diode fault detection, and temperature alert function.
The TMP411 is available in both MSOP-8 and SO-8
(available Q1 2007) packages.
