Applications Information
Thermal Considerations
The MAX6509/MAX6510 supply current is typically
32礎. When used to drive high-impedance loads, the
devices dissipate negligible power; therefore, the die
temperature is essentially the same as the package
temperature. The key to accurate temperature monitor-
ing is good thermal contact between the MAX6509/
MAX6510 package and the device being monitored. In
some applications, the SOT23-5 and SOT23-6 pack-
ages may be small enough to fit underneath a socketed
礟, allowing the device to monitor the 礟s temperature
directly. Use the monitors output to reset the 礟, assert
an interrupt, or trigger an external alarm. Accurate tem-
perature monitoring depends on the thermal resistance
between the device being monitored and the
MAX6509/MAX6510 die.
The rise in die temperature due to self-heating is given
by the following formula:
擳
J
= P
DISS
?SPAN class="pst MAX6509CAZK-V-T_2292275_3"> ?/SPAN>
JA
where P
DISS
is the power dissipated by the
MAX6509/MAX6510, and ?/DIV>
JA
is the packages thermal
resistance. The typical thermal resistance is 115癈/W
for the SOT23-6 package. To limit the effects of self-
heating, minimize the output currents. For example, if
the MAX6510 sinks 5mA, the output voltage is guaran-
teed to be less than 0.3V; therefore, an additional
1.5mW of power is dissipated within the IC. This corre-
sponds to a 0.173癈 shift in the die temperature in the
SOT23-6.
Temperature-Window Detector
The MAX6509/MAX6510 temperature switch outputs
assert when the die temperature is outside the pro-
grammed range. Combining the outputs of a set-cold
and a set-hot device creates an over/undertemperature
detector. The MAX6509/MAX6510 are designed to form
two complementary pairs, each containing one cold trip
point output and one hot trip point output. The assertion
of either output alerts the system to an out-of-range tem-
perature. The MAX6510 push-pull output stages can be
ORed to produce a thermal out-of-range alarm. More
favorably, a MAX6509HAUK+T and MAX6509CAUK+T
can be directly wire-ORed with a single external resis-
tor to accomplish the same task (Figure 5).
The temperature window (alarms or detectors as in
Figure 5) can be used to accurately determine when a
devices temperature falls out of a programmed range,
for example -3癈 to +75癈 as shown in Figure 5. The
thermal overrange signal can be used to assert a ther-
mal shutdown, power-up, recalibration, or other tem-
perature-dependent function.
