3 Description

The TMP411 device 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

device

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 device are:

series resistance cancellation, programmable non-

ideality

factor,

programmable

resolution,

programmable threshold limits, user-defined offset

register

for

maximum

accuracy,

minimum

and

maximum

temperature

monitors,

wide

remote

temperature measurement range (up to 150°C), diode

fault detection, and temperature alert function.

The TMP411 device is available in VSSOP-8 and

SOIC-8 packages.
