MAX6509CAUK-MAX6509CAUK+T-MAX6509HAUK+T-MAX6510HAUT-MAX6510HAUT+T
Resistor-Programmable SOT Temperature Switches
General Description
The MAX6509/MAX6510 are fully integrated, resistor-
programmable temperature switches with thresholds set
by an external resistor. They require only one external
resistor to set the temperature threshold within a wide
-40°C to +125°C temperature range. The MAX6509 pro-
vides an open-drain output. The MAX6510 features three
selectable output options: active-low, active-high, and
open drain with an internal pull-up resistor.
These switches operate with a +2.7V to +5.5V single
supply while providing a temperature threshold accuracy
of ±0.5°C (typ) or ±4.7°C (max). They typically consume
32µA supply current. Hysteresis is pin selectable to 2°C
or 10°C.
The MAX6509/MAX6510 re available in 5-pin and 6-pin
SOT23 packages, respectively.

Typical Operating Characteristics
Detailed Description
The MAX6509/MAX6510 fully integrated temperature
switches incorporate two temperature-dependent refer-
ences and one comparator. One reference exhibits a
positive temperature coefficient, and the other has a
negative temperature coefficient. The temperature at
which the two reference voltages are equal determines
the temperature trip point. Pin-selectable 2°C or 10°C
hysteresis keeps the output from oscillating when the
temperature is close to the threshold. The MAX6509
has an active-low, open-drain output structure that can
only sink current. The MAX6510 has three different out-
put options from which to choose (Table 1).
The MAX6509/MAX6510 are programmable for a wide
range of temperature thresholds from -40°C to +125°C.
The temperature threshold is set by an external resis-
tor between SET and GND. The MAX6509 output easily
interfaces with a microprocessor (µP) reset input
(Figure 2). The MAX6510 output is intended for applica-
tions such as driving a fan control switch (Figure 3).
Hysteresis Input

The HYST pin is a CMOS-compatible input that selects
hysteresis at either a high level (10°C for HYST = VCC)
or a low level (2°C for HYST = GND). Hysteresis prevents
the output from oscillating when the temperature is near
the trip point. Do not leave HYST unconnected. Connect
HYST to GND or VCC. Other input voltages cause
increased supply current.
Choose the set-hot temperature (H) or set-cold tempera-
ture (C) option to ensure that the trip point is accurate
and the hysteresis is in the right direction. A MAX6509
or MAX6510 with the H suffix will first trip at the correct
point when temperature is increasing. For example, a
MAX6509HAUK+T or MAX6510HAUT+T with its trip
point set to 100°C will assert when its temperature rises
above +100°C, and will not deassert until its tempera-
ture drops below +100°C minus the selected hysteresis
value (e.g., +98°C if 2°C hysteresis is chosen). Con-
versely, if the trip temperature of a MAX6509CAUK+T
or MAX6510CAUT+T is -40°C, the output asserts at
-40°C as temperature falls, and deasserts when tem-
perature rises above -40°C plus the hysteresis value (e.g.,
-38°C if 2°C hysteresis is chosen) as shown in Figure 4.
Output Selection

The MAX6509 provides an open-drain output. The
MAX6510 features three output options selectable by
OUTSET (Table 1).

Applications Information
Thermal Considerations

The MAX6509/MAX6510 supply current is typically
32µA. 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
P, allowing the device to monitor the µP’s temperature
directly. Use the monitor’s output to reset the µP, 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:
∆TJ = PDISS · θ JA
where PDISS is the power dissipated by the MAX6509/
MAX6510, and qJA is the package’s thermal resistance.
The typical thermal resistance is 115°C/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 guaranteed to be less than
0.3V; therefore, an additional 1.5mW of power is dissi-
pated within the IC. This corresponds to a 0.173°C 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 resistor
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
device’s temperature falls out of a programmed range,
for example -3°C to +75°C 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.
