Low-Cost, Fail-Safe Temperature
In high-performance/high-reliability applications, multi-
ple temperature monitoring is important. The high-level
integration and low cost of the MAX6516 and MAX6518
facilitate the use of multiple temperature monitors to
increase system reliability. The application in Figure 3
uses two MAX6516s with different hot temperature
thresholds to ensure that fault conditions that can
overheat the monitored device cause no permanent
damage. The first temperature monitor activates the fan
when the die temperature exceeds +45
°
C. The second
MAX6516 triggers a system shutdown if the die
temperature reaches +75
°
C, preventing damage from
a wide variety of destructive fault conditions, including
latchups, short circuits, and cooling-system failures.
PC Board Testing
The MAX6516
–
MAX6519 temp sensor devices can be
tested after PC board assembly using OUT. Testing
can be used to verify proper assembly and functionality
of the temperature protection circuitry. Since OUT has
a weak drive capability, the voltage at OUT can be
forced to cause the digital outputs to change states,
thereby verifying that the internal comparators and out-
put circuitry function properly after assembly. Below is
a test procedure that can be used to test the
MAX6516
–
MAX6519:
Power up the device, measure OUT, and observe the
state of the logic output.
