Name: TMP411DBQDDFRQ1
Brand: Texas Instruments
SKU: TMP411DBQDDFRQ1

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.
