3 Description

The TMP411 and TMP411D devices are remote

temperature sensors with a built-in local temperature

sensor. The remote temperature sensor, diodeconnected

transistors are typically low-cost, NPN- or

PNP-type transistors or diodes that are an integral

part of microcontrollers, microprocessors, or FPGAs.

Remote temperature accuracy is ±1°C (TMP411) or

±0.8°C (TMP411D) 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 and

TMP411D devices are: series resistance cancellation,

programmable non-ideality factor, programmable

resolution, programmable threshold limits, userdefined

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 and TMP411D is available in

SOT23-8 package.
