General Description
The MAX6695/MAX6696 are precise, dual-remote, and
local digital temperature sensors. They accurately mea-
sure the temperature of their own die and two remote
diode-connected transistors, and report the tempera-
ture in digital form on a 2-wire serial interface. The
remote diode is typically the emitter-base junction of a
common-collector PNP on a CPU, FPGA, GPU, or ASIC.
The 2-wire serial interface accepts standard system
management bus (SMBus) commands such as Write
Byte, Read Byte, Send Byte, and Receive Byte to read
the temperature data and program the alarm thresholds
and conversion rate. The MAX6695/MAX6696 can func-
tion autonomously with a programmable conversion
rate, which allows control of supply current and temper-
ature update rate to match system needs. For conver-
sion rates of 2Hz or less, the temperature is
represented as 10 bits + sign with a resolution of
+0.125癈. When the conversion rate is 4Hz, output data
is 7 bits + sign with a resolution of +1癈. The MAX6695/
MAX6696 also include an SMBus timeout feature to
enhance system reliability.
Remote temperature sensing accuracy is ?.5癈 be-
tween +60癈 and +100癈 with no calibration needed.
The MAX6695/MAX6696 measure temperatures from
-40癈 to +125癈. In addition to the SMBus ALERT out-
put, the MAX6695/MAX6696 feature two overtempera-
ture limit indicators (OT1 and OT2), which are active
only while the temperature is above the corresponding
programmable temperature limits. The OT1 and OT2
outputs are typically used for fan control, clock throt-
tling, or system shutdown.
The MAX6695 has a fixed SMBus address. The
MAX6696 has nine different pin-selectable SMBus
addresses. The MAX6695 is available in a 10-pin
糓AX
?/DIV>
and the MAX6696 is available in a 16-pin QSOP
package. Both operate throughout the -40癈 to +125癈
temperature range.
