Local/Remote Temperature Switches in a  
µMAX Package  
General Description  
Features  
The MAX6687/MAX6688 comprise a remote-junction  
temperature switch and a local temperature switch in a  
single package. The remote-junction switch uses an  
external P-N junction (typically a diode-connected tran-  
sistor on the die of an external CPU, ASIC, or FPGA) as  
a sensing element to measure the remote temperature.  
The remote-junction temperature switch has a factory-  
programmed trip temperature threshold of either  
+120°C or +125°C. The local temperature switch has a  
pin-programmable temperature threshold that is set by  
ꢀ Pin-Programmable Local Temperature Threshold  
in 5°C Increments in Two Distinct Ranges: +40°C  
to +80°C and +75°C to +115°C  
ꢀ Factory-Programmed Remote Threshold:  
+120°C (L Suffix) or +125°C (H Suffix)  
ꢀ Open-Drain Active-Low Outputs (MAX6687)

connecting pins S1 and S2 to ground, to V , or leav-

ing them floating. Hysteresis for both local and remote  
thresholds is 5°C. The MAX6687/MAX6688 do not  
assert on transient (single-sample) faults or when  
power is first applied.

ꢀ 215µA Average Supply Current  
ꢀ 3ꢀ0V to 5ꢀ5V Power-Supply Voltage  
ꢀ 8-Pin µMAX Package  
The MAX6687 has two open-drain active-low outputs  
while the MAX6688 has two push-pull active-high out-  
puts. T  
asserts a logic signal when the remote  
REMOTE  
temperature exceeds the factory-programmed +120°C  
or +125°C trip threshold. T is asserted when the

LOCAL  
die temperature exceeds the pin-programmed thresh-  
old, which is controlled by pins S1 and S2. The local  
thresholds are available in two ranges in 5°C incre-  
ments. The two ranges are +40°C to +80°C and +75°C  
to +115°C.
