DESCRIPTION

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 (h-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.
