DESCRIPTION
The TMP401 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 ?癈 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 alarm thresholds and
to read temperature data.
Features included in the TMP401 are series resistance
cancellation, wide remote temperature measurement
range (up to +150癈), diode fault detection, and
temperature alert functions.
