NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation at or
above this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.
2
Digital inputs are protected; however, permanent damage may occur on
unpro-
tected units from high energy electrostatic fields. Keep units in conductive foam
or packaging at all times until ready to use. Use proper antistatic handling
procedures.
3
Remove power before inserting or removing units from their sockets.

FUNCTIONAL DESCRIPTION
An equivalent circuit for the TMP3x family of micropower,
centigrade temperature sensors is shown in Figure 2. At the
heart of the temperature sensor is a band gap core, which is
comprised of transistors Q1 and Q2, biased by Q3 to approxi-
mately 8
μ
A. The band gap core operates both Q1 and Q2 at the
same collector current level; however, since the emitter area of
Q1 is 10 times that of Q2, Q1’s V
BE
and Q2’s V
BE
are not equal
by the following relationship:

Equivalent Circuit
Resistors R1 and R2 are used to scale this result to produce the
output voltage transfer characteristic of each temperature sensor
and, simultaneously, R2 and R3 are used to scale Q1’s V

between the three temperature sensors’ output characteristics.

The output voltage of the temperature sensor is available at the
emitter of Q4, which buffers the band gap core and provides
load current drive. Q4’s current gain, working with the available
base current drive from the previous stage, sets the short-circuit
current limit of these devices to 250
μ
A.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the TMP35/TMP36/TMP37 features proprietary ESD protection circuitry, permanent damage
may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
