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)

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.

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

temperature exceeds the factory-programmed +120°C

or +125°C trip threshold. T is asserted when the

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.
