Low-Cost, Fail-Safe Temperature Monitor
In high-performance/high-reliability applications, multi-
ple temperature monitoring is important. The high-level
integration and low cost of the MAX6509/MAX6510
facilitate the use of multiple temperature monitors to
increase system reliability. Figure 6 shows two
MAX6510s with different temperature thresholds. This
ensures that fault conditions that can overheat the mon-
itored device cause no permanent damage. The first
temperature monitor activates the fan when the die
temperature exceeds +45癈. The second MAX6510
triggers a system shutdown if the die temperature
reaches +75癈. The second temperature monitors out-
put asserts when a wide variety of destructive fault con-
ditions occur, including latchups, short circuits, and
cooling-system failures.
Set-Point Resistor
To set the trip-point temperature, connect a resistor
between SET and GND. The resistors value is deter-
mined either from the R
SET
vs. Temperature graphs
(see Typical Operating Characteristics) or from the
equations below.
To set the temperature trip point from -40癈 to 0癈, use
the following equation:
R
SET(k?
= [(1.3258 ?/SPAN> 10
5
) / (T+1.3)] - 310.1693 -
[(5.7797 ?/SPAN> 10
6
) / (T+1.3)
2
]
To set the temperature trip point from 0癈 to +125癈,
use the following equation:
R
SET(k?
= [(8.3793 ?/SPAN> 10
4
) / T] - 211.3569 +
[(1.2989 ?/SPAN> 10
5
) / T
2
]
where T is the trip temperature in Kelvin.
