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.
