DESCRIPTION
The TMP411-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 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 that are included in the TMP411-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 an VSSOP-8
package.
