3 Description

The TMP411-Q1/TMP411D-Q1 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 (TMP411-Q1) or ±0.8°C

(TMP411D-Q1) 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 included in the TMP411-Q1/TMP411D-Q1

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-Q1 is available in a VSSOP-8 package,

and the TMP411D-Q1 is available in an SOT23-8

package.
