MAX642  
General Description  
Features  
The MAX6642 precise, two-channel digital temperature  
sensor accurately measures the temperature of its own  
die and a remote PN junction and reports the tempera-  
ture data over a 2-wire serial interface. The remote PN  
junction is typically a substrate PNP transistor on the  
die of a CPU, ASIC, GPU, or FPGA. The remote PN  
junction can also be a discrete diode-connected small-  
signal transistor.  
o Dual Channel: Measures Remote and Local  
Temperature  
o +0.25°C Resolution  
o High Accuracy 1°C (max) (Remote) and  
2°C (Local) from +60°C to +100°C  
o Measures Remote Temperature Up to +150°C  
o Programmable Overtemperature Alarm  
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.  
Temperature Thresholds  
o SMBus/I2C-Compatible Interface  
o Tiny TDFN Package with Exposed Pad

Measurements can be done autonomously or in a sin-  
gle-shot mode.  
Remote accuracy is 1°C maꢀimum 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 with an eꢀposed pad.  
T = Tape and reel.  
*EP = Eꢀposed pad.
