General Description  
Features  
o Dual Channel Measures Remote and Local  
The MAX6657/MAX6658/MAX6659 are precise, two-  
channel digital temperature sensors. Each accurately  
measures the temperature of its own die and one  
remote PN junction, and reports the temperature in digi-  
tal form on a 2-wire serial interface. The remote junction  
can be a diode-connected transistor like the low-cost  
NPN type 2N3904 or 2N3906 PNP type. The remote  
junction can also be a common-collector PNP, such as  
a substrate PNP of a microprocessor.  
Temperature  
o 11-Bit, +0.125°C Resolution  
o High Accuracy 1°C (max) from +60°C to +100°C  
(Remote)  
o No Calibration Required  
o Programmable Under/Overtemperature Alarms  
o Programmable Conversion Rate  
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 MAX6657/MAX6658/  
MAX6659 can function autonomously with a program-  
mable conversion rate, which allows the control of sup-  
ply current and temperature update rate to match  
system needs. For conversion rates of 4Hz or less, the  
temperature is represented in extended mode as 10  
bits + sign with a resolution of 0.125°C. When the con-  
version rate is faster than 4Hz, output data is 7 bits +  
sign with a resolution of 1°C. The MAX6657/  
MAX6658/MAX6659 also include an SMBus timeout  
feature to enhance system reliability.  
(0.0625Hz to 16Hz)  
o SMBus/I2C-Compatible Interface  
o Two Alarm Outputs: ALERT and OVERT1  
(MAX6657 and MAX6658)  
o Three Alarm Outputs: ALERT, OVERT1,  
and OVERT2 (MAX6659)  
o Compatible with 65nm Process Technology

Remote accuracy is 1°C between +60°C and +100°C  
with no calibration needed. The MAX6657 measures  
temperatures from 0°C to +125°C and the MAX6658/  
MAX6659 from -55°C to +125°C. The MAX6659 has the  
added benefit of being able to select one of three  
addresses through an address pin, and a second over-  
temperature alarm pin for greater system reliability.
