GENERAL DESCRIPTION
The TMP05/TMP06 are monolithic temperature sensors that
generate a modulated serial digital output (PWM), which varies
in direct proportion to the temperature of the devices. The high
period (T
while the low period (T
higher temperature accuracy of ±1°C from 0°C to 70°C with
excellent transducer linearity. The digital output of the TMP05/
TMP06 is CMOS/TTL compatible, and is easily interfaced to
the serial inputs of most popular microprocessors. The flexible
open-drain output of the TMP06 is capable of sinking 5 mA.
The TMP05/TMP06 are specified for operation at supply
voltages from 3 V to 5.5 V. Operating at 3.3 V, the supply current
is typically 370 µA. The TMP05/TMP06 are rated for operation
over the –40°C to +150°C temperature range. It is not recommended to operate these devices at temperatures above 125°C
for more than a total of 5% (5,000 hours) of the lifetime of the
devices. They are packaged in low cost, low area SC-70 and
SOT-23 packages.

The TMP05/TMP06 have three modes of operation: continuously converting mode, daisy-chain mode, and one shot mode.
A three-state FUNC input determines the mode in which the
TMP05/TMP06 operate.
The CONV/IN input pin is used to determine the rate with
which the TMP05/TMP06 measure temperature in continuously converting mode and one shot mode. In daisy-chain
mode, the CONV/IN pin operates as the input to the daisy
chain.
PRODUCT HIGHLIGHTS
1. The TMP05/TMP06 have an on-chip temperature sensor
that allows an accurate measurement of the ambient
temperature. The measurable temperature range is –40°C
to +150°C.
2. Supply voltage is 3.0 V to 5.5 V.
3. Space-saving 5-lead SOT-23 and SC-70 packages.
4. Temperature accuracy is typically ±0.5°C. The part needs a
decoupling capacitor to achieve this accuracy.
5. 0.025°C temperature resolution.
6. The TMP05/TMP06 feature a one shot mode that reduces
the average power consumption to 102 µW at 1 SPS.

TMP05/TMP06
THEORY OF OPERATION
CIRCUIT INFORMATION
The TMP05/TMP06 are monolithic temperature sensors that
generate a modulated serial digital output that varies in direct
proportion with the temperature of the device. An on-board
sensor generates a voltage precisely proportional to absolute
temperature, which is compared to an internal voltage reference
and is input to a precision digital modulator. The ratiometric
encoding format of the serial digital output is independent of
the clock drift errors common to most serial modulation
techniques such as voltage-to-frequency converters. Overall
accuracy for the A Grade is ±2°C from 0°C to +70°C, with
excellent transducer linearity. B Grade accuracy is ±1°C from
25°C to 70°C. The digital output of the TMP05 is CMOS/TTL
compatible, and is easily interfaced to the serial inputs of most
popular microprocessors. The open-drain output of the TMP06
is capable of sinking 5 mA.
The on-board temperature sensor has excellent accuracy and
linearity over the entire rated temperature range without
correction or calibration by the user.
The sensor output is digitized by a first-order Σ-∆ modulator,
also known as the charge balance type analog-to-digital
converter. This type of converter utilizes time-domain oversampling and a high accuracy comparator to deliver 12 bits of
effective accuracy in an extremely compact circuit.
CONVERTER DETAILS
The Σ-∆ modulator consists of an input sampler, a summing
network, an integrator, a comparator, and a 1-bit DAC. Similar
to the voltage-to-frequency converter, this architecture creates,
in effect, a negative feedback loop whose intent is to minimize
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, which 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.

(SINGLE-BIT)
The modulated output of the comparator is encoded using a
circuit technique that results in a serial digital signal with a
mark-space ratio format. This format is easily decoded by any
microprocessor into either °C or °F values, and is readily
transmitted or modulated over a single wire. More importantly,
this encoding method neatly avoids major error sources
common to other modulation techniques, because it is clockindependent.
FUNCTIONAL DESCRIPTION
The output of the TMP05/TMP06 is a square wave with a
typical period of 116 ms at 25°C (CONV/IN pin is left floating).
The high period, T
, is const ant, while the low period, TL, varies
H
with measured temperature. The output format for the nominal
conversion rate is readily decoded by the user as follows:
Temp e rature (°C) = 421 − (751 × (T
)) (1)
H/TL

The time periods TH (high period) and TL (low period) are
values easily read by a microprocessor timer/counter port, with
the above calculations performed in software. Because both
periods are obtained consecutively using the same clock,
performing the division indicated in the previous formula
results in a ratiometric value that is independent of the exact
frequency or drift of either the originating clock of the TMP05/
TMP06 or the user’s counting clock.
OPERATING MODES
The user can program the TMP05/TMP06 to operate in three
different modes by configuring the FUNC pin on power-up as
either low, floating, or high.
Table 6. Operating Modes

High Daisy-chain
Continuously Converting Mode
In continuously converting mode, the TMP05/TMP06 continuously output a square wave representing temperature. The
frequency at which this square wave is output is determined by
the state of the CONV/IN pin on power-up. Any change to the
state of the CONV/IN pin after power-up is not reflected in the
parts until the TMP05/TMP06 are powered down and back up.

TMP05/TMP06
One Shot Mode
In one shot mode, the TMP05/TMP06 output one square wave
representing temperature when requested by the microcontroller. The microcontroller pulls the OUT pin low and then
releases it to indicate to the TMP05/TMP06 that an output is
required. The temperature measurement is output when the
OUT line is released by the microcontroller (see Figure 23).

In the TMP05 one shot mode only, an internal resistor is
switched in series with the pull-up MOSFET. The TMP05 OUT
pin has a push-pull output configuration (see Figure 24), and,
therefore, needs a series resistor to limit the current drawn on
this pin when the user pulls it low to start a temperature
conversion. This series resistance prevents any short circuit
from V
to GND, and, therefore, protects the TMP05 from
DD
short-circuit damage.

Conversion Rate
In continuously converting and one shot modes, the state of the
CONV/IN pin on power-up determines the rate at which the
TMP05/TMP06 measure temperature. The available conversion
rates are shown in Table 7.

The TMP05 (push-pull output) advantage when using the high
state conversion rate (double high/quarter low) is lower power
consumption. However, the trade-off is loss of resolution on the
low time. Depending on the state of the CONV/IN pin, two
different temperature equations must be used.
The temperature equation for the low and floating states’
conversion rates is
Setting the FUNC pin to a high state allows multiple TMP05/
TMP06s to be connected together and, therefore, allows one
input line of the microcontroller to be the sole receiver of all
temperature measurements. In this mode, the CONV/IN pin
operates as the input of the daisy chain, and conversions take
place at the nominal conversion rate of T
= 40 ms/ 76 ms

Therefore, the temperature equation for the daisy-chain mode

Figure 25. Daisy-Chain Structure
A second microcontroller line is needed to generate the conversion start pulse on the CONV/IN pin. The pulse width of the
start pulse should be less than 25 µs. The start pulse on the
CONV/IN pin lets the first TMP05/TMP06 part know that it
should start a conversion and output its own temperature now.
Once the part has output its own temperature, it then outputs a
start pulse for the next part on the daisy-chain link. The pulse
width of the start pulse from each TMP05/TMP06 part is
typically 17 µs.
Figure 26 shows the start pulse on the CONV/IN pin of the first
device on the daisy chain and Figure 27 shows the PWM output
by this first part.

TIME
Before the start pulse reaches a TMP05/TMP06 part in the
daisy chain, the device acts as a buffer for the previous temperature measurement signals. Each part monitors the PWM signal
for the start pulse from the previous part. Once the part detects
the start pulse, it initiates a conversion and inserts the result at
the end of the daisy-chain PWM signal. It then inserts a start
pulse for the next part in the link. The final signal input to the
microcontroller should look like Figure 28. The input signal on
Pin 2 (IN) of the first daisy-chain device must remain low until
the last device has output its start pulse.
If the input on Pin 2 (IN) goes high and remains high, the
TMP05/TMP06 part powers down between 0.3 s and 1.2 s later.
The part, therefore, requires another start pulse to generate
another temperature measurement. Note that, to reduce power
dissipation through the part, it is recommended to keep Pin 2
(IN) at a high state when the part is not converting. If the IN
pin is at 0 V, then the OUT pin is at 0 V (because it is acting as a
buffer when not converting), and drawing current through
either the pull-up MOSFET (TMP05) or the pull-up resistor
(TMP06).
TMP05 OUTPUT
The TMP05 has a push-pull CMOS output (Figure 29) and
provides rail-to-rail output drive for logic interfaces. The rise
and fall times of the TMP05 output are closely matched, so that
errors caused by capacitive loading are minimized. If load
capacitance is large (for example, when driving a long cable), an
external buffer might improve accuracy.

APPLICATION HINTS
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 TMP05/TMP06 to settle to the desired
accuracy is dependent on the package selected, the thermal
contact established in that particular application, and the
equivalent power of the heat source. In most applications, the
settling time is probably best determined empirically.
SELF-HEATING EFFECTS
The temperature measurement accuracy of the TMP05/TMP06
might be degraded in some applications due to self-heating.
Errors introduced are from the quiescent dissipation and power
dissipated when converting, that is, during T
these temperature errors is dependent on the thermal conductivity of the TMP05/TMP06 package, the mounting technique,
and the effects of airflow. Static dissipation in the TMP05/
TMP06 is typically 10 W operating at 3.3 V with no load. In the
5-lead SC-70 package mounted in free air, this accounts for a
temperature increase due to self-heating of
ΔT = P
× θJA = 10 µW × 211.4°C/W = 0.0021°C (5)
DISS
In addition, power is dissipated by the digital output, which is
capable of sinking 800 µA continuously (TMP05). Under an
800 µA load, the output can dissipate
= (0.4 V)(0.8 mA)((TL)/TH + TL)) (6)
P
DISS
For example, with T
= 80 ms and TH = 40 ms, the power
L
dissipation due to the digital output is approximately 0.21 mW.
In a free-standing SC-70 package, this accounts for a temperature increase due to self-heating of
ΔT = P
× θJA = 0.21 mW × 211.4°C/W = 0.044°C (7)
DISS
This temperature increase adds directly to that from the
quiescent dissipation and affects the accuracy of the TMP05/
TMP06 relative to the true ambient temperature.

SUPPLY DECOUPLING
The TMP05/TMP06 should be decoupled with a 0.1 µF ceramic
capacitor between V
if the TMP05/TMP06 are mounted remotely from the power
supply. Precision analog products such as the TMP05/TMP06
require a well-filtered power source. Because the TMP05/
TMP06 operate from a single supply, it might seem convenient
to simply 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 hundreds of mV in amplitude due to
wiring resistance and inductance.
If possible, the TMP05/TMP06 should be powered directly
from the system power supply. This arrangement, shown in
Figure 31, isolates the analog section from the logic switching
transients. Even if a separate power supply trace is not available,
however, generous supply bypassing reduces supply-lineinduced errors. Local supply bypassing consisting of a 0.1 µF
ceramic capacitor is critical for the temperature accuracy
specifications to be achieved. This decoupling capacitor must
be placed as close as possible to the TMP05/TMP06’s V
A recommended decoupling capacitor is Phicomp’s 100 nF,
50 V X74.
Keep the capacitor package size as small as possible, because
ESL (equivalent series inductance) increases with increasing
package size. Reducing the capacitive value below 100 nF
increases the ESR (equivalent series resistance). Use of a
capacitor with an ESL of 1 nH and an ESR of 80 mΩ is
recommended.

TEMPERATURE MONITORING
The TMP05/TMP06 are ideal for monitoring the thermal
environment within electronic equipment. For example, the
surface-mounted package accurately reflects the exact thermal
conditions that affect nearby integrated circuits.
The TMP05/TMP06 measure and convert the temperature at
the surface of their own semiconductor chip. When the TMP05/
TMP06 are used to measure the temperature of a nearby heat
source, the thermal impedance between the heat source and the
TMP05/TMP06 must be considered. Often, a thermocouple or
other temperature sensor is used to measure the temperature of
the source, while the TMP05/TMP06 temperature is monitored
by measuring T
mined, the temperature of the heat source can be inferred from
the TMP05/TMP06 output.
One example of using the TMP05/TMP06’s unique properties is
in monitoring a high power dissipation microprocessor. The
TMP05/TMP06 part, in a surface-mounted package, is mounted
directly beneath the microprocessor’s pin grid array (PGA)
package. In a typical application, the TMP05/TMP06’s output is
connected to an ASIC, where the pulse width is measured. The
TMP05/TMP06 pulse output provides a significant advantage in
this application, because it produces a linear temperature output
while needing only one I/O pin and without requiring an ADC.

DAISY-CHAIN APPLICATION
This section provides an example of how to connect two
TMP05s in daisy-chain mode to a standard 8052 microcontroller core. The ADuC812 is the microcontroller used in the
following example and has the 8052 as its core processing
engine. Figure 32 shows how to interface to the 8052 core
device. TMP05 Program Code Example 1 shows how to
communicate from the ADuC812 to the two daisy-chained
TMP05s. This code can also be used with the ADuC831 or any
microprocessor running on an 8052 core.
