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°C. The second MAX6510
triggers a system shutdown if the die temperature
reaches +75°C. The second temperature monitor’s 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 resistor’s value is deter-
mined either from the RSET vs. Temperature graphs
(see Typical Operating Characteristics) or from the
equations below.
To set the temperature trip point from -40°C to 0°C, use
the following equation:
RSET(k) = [(1.3258 105) / (T+1.3)] - 310.1693 -
[(5.7797 106) / (T+1.3)2]
To set the temperature trip point from 0°C to +125°C,
use the following equation:
RSET(k) = [(8.3793 104) / T] - 211.3569 +
[(1.2989 105) / T2]
where T is the trip temperature in Kelvin.
