TMP401
SBOS371B –AUGUST 2006–REVISED OCTOBER 2014
TMP401 ±1°C Programmable, Remote and Local, Digital Out Temperature Sensor
1 Features 3 Description
The TMP401 is a remote temperature sensor monitor
1
• ±1°C Remote Diode Sensor
with a built-in local temperature sensor. The remote
• ±3°C Local Temperature Sensor
sensor is capable of monitoring the temperature of
• Series Resistance Cancellation
any external PN junction. Typical sense elements
include low-cost NPN- or PNP-type transistors and
• THERM Flag Output
diodes, or accessible thermal diodes integrated within
• ALERT/THERM2 Flag Output
microcontrollers, microprocessors, or field-
• Programmable Over- and Undertemperature
programmable gate arrays (FPGAs).
Limits
The accuracy of the remote sensor is ±1°C for
• Programmable Resolution: 9- to 12-Bit
multiple IC manufacturers, with no calibration needed.
• Diode Fault Detection
The two-wire serial interface accepts SMBus write
byte, read byte, send byte, and receive byte
• SMBus-Compatible
commands to program alarm thresholds and to read
temperature data.
2 Applications
Features included in the TMP401 are series
• Servers and Workstations
resistance cancellation, wide remote temperature
• Desktop and Notebook Computers
measurement range (up to +150°C), diode fault
• Telecom and Network Infrastructure
detection, and temperature alert functions.
