The TMP441 and TMP442 are remote temperature monitors with a built-in local temperature sensor. 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 field-programmable gate arrays (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 configure the device.

The TMP441 has a single remote temperature monitor with address pins. The TMP442 has dual remote temperature monitors, and is available with two different interface addresses. All versions include automatic beta compensation (correction), series resistance cancellation, programmable non-ideality factor (-factor), wide remote temperature measurement range (up to +150°C), and diode fault detection.

The TMP441 and TMP442 are both available in an 8-lead, SOT23 package.
