General Description
The MAX6516–MAX6519 low-cost, fully integrated temperature 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 temperature 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 (typ). These devices require no external components and typically consume 22µA of supply current.
Hysteresis is pin selectable at 2°C or 10°C.
The MAX6516–MAX6519 are offered with hot-temperature thresholds (+35°C to +115°C), asserting when the
temperature is above the threshold, or with cold-temperature thresholds (-45°C to +15°C), 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 required.
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 available in a space-saving 5-pin SOT23 package and operate over the -55°C to +125°C temperature range.

Detailed Description
The MAX6516–MAX6519 fully integrated temperature
switches incorporate a fixed reference, an analog temperature sensor, and a comparator. The temperature at
which the two reference voltages are equal 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 circuit guarantees the logic output is at its +25°C state for
at least 50µs.
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 approximately linear and can be described by the quadratic
equation:
V
OUT
= 1.8015 - 10.62mV (T - 30) + 1.1µV (T - 30)
2
where T = temperature in °C.
In most cases, a linear approximation can be applied:
V
OUT
= 1.8015 - 10.62mV (T - 30)
Therefore,
Hysteresis Input
The HYST input selects the devices’ temperature hysteresis and prevents the output from oscillating when the
temperature approaches the trip point. Connect HYST to
VCCfor 2°C hysteresis or to GND for 10°C hysteresis.
Logic Temperature Indicators
Overtemperature Indicator (Hot Thresholds)
TOVER and TOVER designations apply to thresholds
above TA= +25°C (+35°C, +45°C, +55°C, +65°C, +75°C,
+85°C, +95°C, +105°C, +115°C). All “hot” thresholds are
positive temperatures.
The overtemperature indicator output is open-drain
active low (TOVER) or push-pull active high (TOVER).
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 temperature threshold.
Undertemperature Indicator (Cold Thresholds)
TUNDER and TUNDER designations apply to thresholds
below TA= +25°C (+15°C, +5°C, -5°C, -15°C, -25°C,
-35°C, -45°C). The undertemperature indicator output is
open drain, active low (TUNDER), or push-pull active
high (TUNDER). TUNDER goes low when the die temperature goes below the factory-programmed temperature threshold. TUNDER should be pulled up to a
voltage no greater than 5.5V with a 100kΩ pullup resistor. 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
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 1).
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.

Low-Cost, Fail-Safe Temperature
In high-performance/high-reliability applications, multiple 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 output circuitry function properly after assembly. Below is
a test procedure that can be used to test the
MAX6516–MAX6519:
• Power up the device, measure OUT, and observe the
state of the logic output.

• Calculate the temperature using the formula:
• Verify that the temperature measured is within ±2°C
of the ambient board temperature. Measure the
ambient board temperature using an accurate calibrated temperature sensor.
• Connect OUT to ground (OUT to VCCfor cold
threshold versions) and observe the state change of
the logic output.
• Disconnect OUT from ground and observe that the
logic output reverts to its initial state.
Hysteresis Testing
The MAX6516–MAX6519 can be programmed with 2°C
or 10°C of hysteresis by pin strapping HYST to VCCor
GND, respectively. Below is a test feature that can be
used to measure the accuracy of the device’s hysteresis using a device with a +65°C threshold:
• Power up the device and observe the state of the
digital output.
• Drive the OUT voltage down gradually.
• When the digital output changes state, note V

.
•V

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 temperature is essentially the same as the package temperature.
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 quickly
and reliably. The rise in die temperature due to self-heating is given by the following formula:
ΔT
J
= P
DISSIPATION
✕ θ
JA
where P
DISSIPATION
is the power dissipated by the
MAX6516–MAX6519, and θJAis the thermal resistance
of the package.
The typical thermal resistance is 140°C/W for the
5-pin SOT23 package. To limit the effects of selfheating, 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 temperature in the 5-pin SOT23 package.
