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.
