GENERAL DES°RIPTION
The ADT6401/ADT6402 are trip point temperature switches
available in a 6-lead SOT-23 package. Each part contains an
internal band gap temperature sensor for local temperature
sensing. When the temperature crosses the trip point setting,
the logic output is activated. The ADT6401 logic output is
active low and open-drain. The ADT6402 logic output is active
high and push-pull. The temperature is digitized to a resolution
of 0.125°C (11-bit). The pin-selectable trip point settings are
10°C apart starting from −45°C to +5°C for undertemperature
switching, and from 45°C to 115°C for overtemperature
switching.
When the ADT6401/ADT6402 are used for monitoring tempera-
tures from −45°C to +5°C, the logic output pin becomes active
when the temperature goes lower than the selected trip point
temperature.
PRODU°T HIGHLIGHTS
1. Σ-Δ based temperature measurement gives high accuracy
and noise immunity.
2. Wide operating temperature range from −55°C to +125°C.
3.

4. Pin-selectable threshold settings from −45°C to +115°C in
10°C increments.
5. Supply voltage is 2.7 V to 5.5 V.
These devices typically consume 30 μA of supply current. Hystere-
sis is pin selectable at 2°C and 10°C. The temperature switch is
specified to operate over the supply range of 2.7 V to 5.5 V.
6. Supply current of 30 μA.
7. Space-saving, 6-lead SOT-23 package.
8. Pin-selectable temperature hysteresis of 2°C or 10°C.
9. Temperature resolution of 0.125°C.

THEORY OF OPERATION
°IR°UIT INFORMATION
PIN-SELE°TABLE TRIP POINT AND HYSTERESIS
The ADT6401/ADT6402 are 11-bit digital temperature sensors
with a 12th bit acting as the sign bit. An on-board temperature
sensor generates a voltage precisely proportional to absolute
temperature, which is compared to an internal voltage reference
and input to a precision digital modulator. The 12-bit output
from the modulator is input into a digital comparator, where it
is compared with a pin-selectable trip level. The output trip pin
is activated if the temperature measured is greater than, or less
than, the pin-selectable trip level. Overall accuracy for the
ADT6401/ ADT6402 is 6°C (maximum) from −45°C to
+115°C.
The temperature trip point and hysteresis values for the
ADT6401/ADT6402 are selected using Pin S0, Pin S1, and
Pin S2. These three pins can be connected to VCC, tied to GND,
or left floating. The ADT6401/ADT6402 decode the inputs on
S0, S1, and S2 to determine the temperature trip point and
hysteresis value, as outlined in Table 4.
The ADT6401 overtemperature/undertemperature output is
intended to interface to reset inputs of microprocessors. The
ADT6402 is intended for driving circuits of applications, such
as fan control circuits.
Table 4. Selecting Trip Points and Hysteresis1
The on-board temperature sensor has excellent accuracy and
linearity over the entire rated temperature range without needing
correction or calibration by the user. The ADT6401 has active
low, open-drain output structures that can sink current. The
ADT6402 has active high, push-pull output structures that can
sink and source current. On power-up, the output becomes
active when the first conversion is completed, which typically
takes 30 ms.

The sensor output is digitized by a first-order, ∑-ꢀ modulator,
also known as the charge balance type analog-to-digital converter
(ADC). This type of converter utilizes time domain oversampling
and a high accuracy comparator to deliver 11 bits of effective
accuracy in an extremely compact circuit.

The Σ-Δ modulator consists of an input sampler, a summing
network, an integrator, a comparator, and a 1-bit digital-to-
analog converter (DAC). Similar to the voltage-to-frequency
converter, this architecture creates a negative feedback loop and
minimizes the integrator output by changing the duty cycle of
the comparator output in response to input voltage changes.
The comparator samples the output of the integrator at a much
higher rate than the input sampling frequency; this is called
oversampling. Oversampling spreads the quantization noise
over a much wider band than that of the input signal, improving
overall noise performance and increasing accuracy.

ADT6401/ADT6402
Hysteresis
This temperature conversion typically takes 30 ms, after which
the analog circuitry of the part automatically shuts down. The
analog circuitry powers up again 570 ms later, when the 600 ms
timer times out and the next conversion begins. The result of
the most recent temperature conversion is compared with the
factory-set trip point value. If the temperature measured is
greater than the trip point value, the output is activated. The
output is deactivated once the temperature crosses back over
the trip point threshold, plus whatever temperature hysteresis is
selected. Figure 18 to Figure 21 show the transfer function for
the output trip pin of each generic model.
A hysteresis value of 2°C or 10°C can be selected. The digital
comparator ensures excellent accuracy for the hysteresis value.
Hysteresis prevents oscillation on the output pin when the
temperature is approaching the trip point and after the output
pin is activated. For example, if the temperature trip is 45°C and
the hysteresis selected is 10°C, the temperature must go as low
as 35°C before the output deactivates.
TEMPERATURE °ONVERSION
The conversion clock for the part is generated internally. No
external clock is required. The internal clock oscillator runs an
automatic conversion sequence. During this automatic conversion
sequence, a conversion is initiated every 600 ms. At this time, the
part powers up its analog circuitry and performs a temperature
conversion.

APPLICATIONS INFORMATION
If possible, the ADT6401/ADT6402 should be powered directly
from the system power supply. This arrangement, shown in
Figure 22, isolates the analog section from the logic-switching
transients. Even if a separate power supply trace is not available,
generous supply bypassing reduces supply line induced errors.
Local supply bypassing consisting of a 0.1 ꢁF ceramic capacitor
is advisable to achieve the temperature accuracy specifications.
This decoupling capacitor must be placed as close as possible to
the ADT6401/ADT6402 VCC pin.
THERMAL RESPONSE TIME
The time required for a temperature sensor to settle to a specified
accuracy is a function of the thermal mass of the sensor and
the thermal conductivity between the sensor and the object
being sensed. Thermal mass is often considered equivalent to
capacitance. Thermal conductivity is commonly specified using
the symbol Q and can be thought of as thermal resistance. It is
commonly specified in units of degrees per watt of power
transferred across the thermal joint. Thus, the time required for
the ADT6401/ADT6402 to settle to the desired accuracy is
dependent on the characteristics of the SOT-23 package, the
thermal contact established in that particular application, and
the equivalent power of the heat source. In most applications,
the settling time is best determined empirically.

SELF-HEATING EFFE°TS
POWER
SUPPLY
The temperature measurement accuracy of the ADT6401/
ADT6402 can be degraded in some applications due to self-
heating. Errors can be introduced from the quiescent dissipation
and power dissipated when converting. The magnitude of these
temperature errors depends on the thermal conductivity of the
ADT6401/ADT6402 package, the mounting technique, and the
effects of airflow. At 25°C, static dissipation in the ADT6401/
ADT6402 is typically 99 ꢁW operating at 3.3 V. In the 6-lead
SOT-23 package mounted in free air, this accounts for a tempera-
ture increase due to self-heating of
Figure 22. Separate Traces Used to Reduce Power Supply Noise
TEMPERATURE MONITORING
The ADT6401/ADT6402 are ideal for monitoring the thermal
environment within electronic equipment. For example, the
surface-mount package accurately reflects the exact thermal
conditions that affect nearby integrated circuits.
The ADT6401/ADT6402 measure and convert the temperature
at the surface of its own semiconductor chip. When the ADT6401/
ADT6402 are used to measure the temperature of a nearby heat
source, the thermal impedance between the heat source and the
ADT6401/ADT6402 must be as low as possible.
ΔT = PDISS × θJA = 99 ꢁW × 240°C/W = 0.024°C
It is recommended that current dissipated through the device be
kept to a minimum because it has a proportional effect on the
temperature error.
As much as 60% of the heat transferred from the heat source to
the thermal sensor on the ADT6401/ADT6402 die is discharged
via the copper tracks, package pins, and bond pads. Of the pins
on the ADT6401/ADT6402, the GND pin transfers most of the
heat. Therefore, to monitor the temperature of a heat source, it is
recommended that the thermal resistance between the ADT6401/
ADT6402 GND pin and the GND of the heat source be reduced
as much as possible.
SUPPLY DE°OUPLING
The ADT6401/ADT6402 should be decoupled with a 0.1 ꢁF
ceramic capacitor between VCC and GND. This is particularly
important when the ADT6401/ADT6402 are mounted remotely
from the power supply. Precision analog products such as the
ADT6401/ADT6402 require well-filtered power sources.
Because the ADT6401/ADT6402 operate from a single supply,
it may seem convenient to tap into the digital logic power supply.
Unfortunately, the logic supply is often a switch-mode design,
which generates noise in the 20 kHz to 1 MHz range. In addition,
fast logic gates can generate glitches that are hundreds of millivolts
in amplitude due to wiring resistance and inductance.
For example, the unique properties of the ADT6401/ADT6402
can be used to monitor a high power dissipation microproces-
sor. The ADT6401/ADT6402 device in its SOT-23 package is
mounted directly beneath the pin grid array (PGA) package of
the microprocessor. The ADT6401/ADT6402 require no external
characterization.
