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 twowire

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 nonideality

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.
