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.
