Low-Cost, 2.7V to 5.5V, Analog Temperature
Sensor Switches in a SOT23
–MAX6519
General Description
Features
The MAX6516–MAX6519 low-cost, fully integrated tem-
perature switches assert a logic signal when their die
temperature crosses a factory-programmed threshold.
Operating from a 2.7V to 5.5V supply, these devices
feature a fixed voltage reference, an analog tempera-
ture sensor, and a comparator. They are available with
factory-trimmed temperature trip thresholds from -45°C
to +115°C in 10°C increments, and are accurate to
0.5°C ꢀtypꢁ. These devices reꢂuire no external compo-
nents and typically consume 22µA of supply current.
Hysteresis is pin selectable at 2°C or 10°C.
♦ High Accuracy 1.5°C (max) Over -15°C to +65°C
Temperature Range
♦ Low Power Consumption—22µA Typical Current
♦ Factory-Programmed Thresholds from -45°C to
+115°C in 10°C Increments
♦ Analog Output to Allow Board-Level Testing
♦ Open-Drain or Push-Pull Outputs
♦ Pin-Selectable 2°C or 10°C Hysteresis
Ordering Information
The MAX6516–MAX6519 are offered with hot-tempera-
ture thresholds ꢀ+35°C to +115°Cꢁ, asserting when the
temperature is above the threshold, or with cold-tem-
perature thresholds ꢀ-45°C to +15°Cꢁ, asserting when
the temperature is below the threshold.

These devices provide an analog output proportional to
temperature and are stable with any capacitive load up
to 1000pF. The MAX6516–MAX6519 can be used over a
range of -35°C to +125°C with a supply voltage of 2.7V
to 5.5V. For applications sensing temperature down to
-45°C, a supply voltage above 4.5V is reꢂuired.
Note: These parts are offered in 16 standard temperature ver-
sions with a minimum order of 2500 pieces. To complete the
suffix information, add P or N for positive or negative trip tem-
perature, and select an available trip point in degrees centi-
grade. For example, the MAX6516UKP065+T describes a
MAX6516 in a 5-pin SOT23 package with a +65°C threshold.
Contact the factory for pricing and availability.
The MAX6516 and MAX6518 have an active-high,
push-pull output. The MAX6517 and MAX6519 have an
active-low, open-drain output. These devices are avail-
able in a space-saving 5-pin SOT23 package and oper-
ate over the -55°C to +125°C temperature range.

Detailed Description
The MAX6516–MAX6519 fully integrated temperature
switches incorporate a fixed reference, an analog tem-
perature sensor, and a comparator. The temperature at
which the two reference voltages are eꢂual determines
the temperature trip point. OUT is an analog voltage
that varies with the die’s temperature. Pin-selectable
2°C or 10°C hysteresis keeps the digital output from
oscillating when the die temperature approaches the
threshold temperature. The MAX6516 and MAX6518
have an active-high, push-pull output structure that can
sink or source current. The MAX6517 and MAX6519
have an active-low, open-drain output structure that
can only sink current. The internal power-on reset cir-
cuit guarantees the logic output is at its +25°C state for
at least 50µs.
The overtemperature indicator output is open-drain
active low ꢀTOVERꢁ or push-pull active high ꢀTOVERꢁ.
TOVER goes low when the die temperature exceeds
the factory-programmed temperature threshold. TOVER
should be pulled up to a voltage no greater than 5.5V
with a 100kΩ pullup resistor. TOVER is a push-pull
active-high CMOS output that goes high when the die
temperature exceeds the factory-programmed temper-
ature threshold.
Undertemperature Indicator (Cold Thresholds)
Analog Output
OUT is an analog output that is proportional to the die
temperature. OUT voltage range is between 0.77V to
2.59V, within the temperature range of -45°C to
+125°C. For applications with a switching threshold of
-45°C, the supply voltage must be greater than 4.5V.
The temperature-to-voltage transfer function is approxi-
mately linear and can be described by the ꢂuadratic
eꢂuation:
TUNDER and TUNDER designations apply to thresholds
below T = +25°C ꢀ+15°C, +5°C, -5°C, -15°C, -25°C,
A
-35°C, -45°Cꢁ. The undertemperature indicator output is
open drain, active low ꢀTUNDERꢁ, or push-pull active
high ꢀTUNDERꢁ. TUNDER goes low when the die tem-
perature goes below the factory-programmed tempera-
ture threshold. TUNDER should be pulled up to a
voltage no greater than 5.5V with a 100kΩ pullup resis-
tor. TUNDER is a push-pull active-high CMOS output
that goes high when the die temperature falls below the
factory-programmed temperature threshold.

Applications Information
where T = temperature in °C.
Temperature-Window Alarm
The MAX6516/MAX6518 logic outputs assert when the
die temperature is outside the factory-programmed
range. Combining the outputs of two devices creates
an over/undertemperature alarm. Two MAX6516s or
two MAX6518s are used to form two complementary
pairs, 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 temperature. The
MAX6516 push-pull output stages can be ORed to
produce a thermal out-of-range alarm ꢀFigure 1ꢁ.
In most cases, a linear approximation can be applied:
V
OUT
= 1.8015 - 10.62mV ꢀT - 30ꢁ
Therefore,
1.8015 − V
OUT
T =
+ 30°C
0.01062
More favorably, two MAX6517s or two MAX6519s can
be directly wire-ORed with a single external resistor to
accomplish the same task. The temperature window
alarms shown in Figure 2 can be used to accurately
determine when a device’s temperature falls out of the
-5°C to +75°C range. The thermal overrange signal can
be used to assert a thermal shutdown, power-up,
recalibration, or other temperature-dependent function.
Hysteresis Input
The HYST input selects the devices’ temperature hys-
teresis and prevents the output from oscillating when the
temperature approaches the trip point. Connect HYST to
V
for 2°C hysteresis or to GND for 10°C hysteresis.

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:

• Calculate the temperature using the formula:
Thermal Considerations
The MAX6516–MAX6519 supply current is typically 22µA.
When used to drive high-impedance loads, the devices
dissipate negligible power. Therefore, the die tempera-
ture is essentially the same as the package temperature.

0.01062
• Verify that the temperature measured is within 2°C
of the ambient board temperature. Measure the
ambient board temperature using an accurate cali-
brated temperature sensor.
Accurate temperature monitoring depends on the thermal
resistance between the device being monitored and the
MAX6516–MAX6519 die. Heat flows in and out of plastic
packages, primarily through the leads. Pin 2 of the 5-pin
SOT23 package provides the lowest thermal resistance to
the die. Short, wide copper traces between the
MAX6516–MAX6519 and the object whose temperature
is being monitored ensures heat transfers occur ꢂuickly
and reliably. The rise in die temperature due to self-heat-
ing is given by the following formula:
• Connect OUT to ground ꢀOUT to V
for cold
CC
threshold versionsꢁ and observe the state change of
the logic output.
• Disconnect OUT from ground and observe that the
logic output reverts to its initial state.

of the package.
The typical thermal resistance is 140°C/W for the
5-pin SOT23 package. To limit the effects of self-
heating, minimize the output current. For example, if the
MAX6516–MAX6519 sink 1mA, the open-drain output
voltage is guaranteed to be less than 0.3V. Therefore,
an additional 0.3mW of power is dissipated within the
IC. This corresponds to a 0.042°C shift in the die tem-
perature in the 5-pin SOT23 package.

Changed the leaded parts to lead(Pb)-free parts in the Ordering Information table; in
the Absolute Maximum Ratings section changed the continuous power dissipation
numbers (7.1mW/°C to 3.1mW/°C and 571mW to 247mW); added the Package
