General Description
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
connecting pins S1 and S2 to ground, to VDD, 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. TREMOTE asserts a logic signal when the remote
temperature exceeds the factory-programmed +120°C
or +125°C trip threshold. TLOCAL 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.
The MAX6687/MAX6688 operate from a 3.0V to 5.5V
power supply and are available in a space-saving 8-pin
MAX package.
