General Description
The MAX6642 is a precise, two-channel digital temper-
ature sensor. It accurately measures the temperature of
its own die and a remote PN junction, and reports the
temperature data over a 2-wire serial interface. The
remote PN junction is typically a substrate PNP transis-
tor on the die of a CPU, ASIC, GPU, or FPGA. The
remote PN junction can also be a discrete diode-con-
nected small-signal transistor.
The 2-wire serial interface accepts standard system
management bus (SMBus), Write Byte, Read Byte,
Send Byte, and Receive Byte commands to read the
temperature data and to program the alarm thresholds.
To enhance system reliability, the MAX6642 includes an
SMBus timeout. The temperature data format is 10 bit
with the least significant bit (LSB) corresponding to
+0.25°C. The ALERT output asserts when the local or
remote overtemperature thresholds are violated. A fault
queue may be used to prevent the ALERT output from
setting until two consecutive faults have been detected.
Measurements can be done autonomously or in a sin-
gle-shot mode.
Remote accuracy is ±1°C maximum error between
+60°C and +100°C. The MAX6642 operates from -40°C
to +125°C, and measures remote temperatures
between 0°C and +150°C. The MAX6642 is available in
a 6-pin TDFN package.
