General Description
Remote and Local Temere Measurements
Do Not Need to Calibrae
The uS5004 is a digital thermometer to monitor both remote
and local temperature, it accurately measures its own
temperature and the remote temperature that mounted
2N3904 diode-connected transistor that can replace
conventional thermistors and thermocouples.

Supply Voltage nge from 3.3V 10%
The standard 2-wire interface System Management Bus
(SMBus) accepts Write byte, Read byte, Send byte, and
Receive byte command to communicate with uS5004. The
device data format of remote temperature measurement is
11bits, with each bit of the extended 3bits corresponding
0.125OC.

Functional Description
RT_MntEn bit low in the configuration register to disable
remote temperature measurem
The uS5004 is a temperature sensor that measures local
and remote temperature by using its own diode and a
mounted diode-connected transistor, and operates by
standard 2-wire SMBus interface.
Standby Mode
Standby mode disables ADC atops conversion when
forcing the MNT_STOP bit hh ionfiguration byte.
In this mode, all data is retained imory that the master
can still read and write by sing SMBus interface, and be
forced to convert once by enteg the one-shot command.
ADC Temperature Measurement
The uS5004 temperature sensor forces currents to both
remote and local diodes, measures their voltages and an
analog to digital converter (ADC) automatically computes
remote and local temperature once the conversion has
started.
One-Shot Register mmand
The one-shot register comand initiates the ADC in
standby mode. IfAC unning when initiates, the previous
data would not bstored. The 0Fh register is written by
using the SMBus te protocol.
ADC Conversion Process
Both channels are simultaneously converted in auto-convert
mode or one-shot command is written, the results of remote
and local temperatures are updated until the end of
conversion. If theADC_Busy status bit is in the busy status,
it meansADC is running a new conversion, but the previous
results are still available. Therefore, if one of remote and
local temperature measurement is not needed, the user
can neglect the result of the unused one or write the
SMBus Intere
The data o00ransfers by using the standard 2-wire
SMBus senecee, write and read protocol.

filter has four state to suppress erroneous remote

RT filter reaction to both step response and an impulse
input response. Besides, user can set theAM bit high into

is over the limit, the ALERT output is low; and it is high
when it is under the limit. Figure 6 shows response of the
comparator mode.
