Data Sheet TMP35/TMP36/TMP37 APPLICATIONS INFORMATION SHUTDOWN OPERATION THERMAL ENVIRONMENT EFFECTS All TMP35/TMP36/TMP37 devices include a shutdown The thermal environment in which the TMP35/TMP36/TMP37 capability, which reduces the power supply drain to less than sensors are used determines two important characteristics: self- 0.5 µA maximum. This feature, available only in the SOIC_N heating effects and thermal response time. Figure 23 illustrates a and the SOT-23 packages, is TTL/CMOS level-compatible, thermal model of the TMP35/TMP36/TMP37 temperature provided that the temperature sensor supply voltage is equal in sensors, which is useful in under-standing these characteristics. magnitude to the logic supply voltage. Internal to the TMP35/ TJ θJC TC θCA TMP36/TMP37 at the SHUTDOWN pin, a pull-up current source to +V is connected. This allows the SHUTDOWN pin to S be driven from an open-collector/drain driver. A logic low, or PD CCH CC TA zero-volt condition, on the SHUTDOWN pin is required to 00337-021 turn off the output stage. During shutdown, the output of the Figure 23. Thermal Circuit Model temperature sensors becomes high impedance where the potential of the output pin is then determined by external In the T-3 package, the thermal resistance junction-to-case, θJC, circuitry. If the shutdown feature is not used, it is recommended is 120°C/W. The thermal resistance case-to-ambient, CA, is the that the SHUTDOWN pin be connected to +V (Pin 8 on the difference between θJA and θJC, and is determined by the char- S acteristics of the thermal connection.

The rise in die temperature above MOUNTING CONSIDERATIONS the ambient temperature of the medium is given by If the TMP35/TMP36/TMP37 temperature sensors are thermally T = P × (θ + θ ) + T J D JC CA A attached and protected, they can be used in any temperature Thus, the die temperature rise of a TMP35 SOT-23 package measurement application where the maximum temperature mounted into a socket in still air at 25°C and driven from a 5 V range of the medium is between −40°C and +125°C. Properly supply is less than 0.04°C. cemented or glued to the surface of the medium, these sensors The transient response of the TMP35/TMP36/TMP37 sensors are within 0.01°C of the surface temperature. Caution should be to a step change in the temperature is determined by the exercised, especially with T-3 packages, because the leads and thermal resistances and the thermal capacities of the die, C , any wiring to the device can act as heat pipes, introducing CH and the case, C . The thermal capacity of C varies with the errors if the surrounding air-surface interface is not isothermal. C C measurement medium because it includes anything in direct Avoiding this condition is easily achieved by dabbing the leads contact with the package. In all practical cases, the thermal of the temper-ature sensor and the hookup wires with a bead of capacity of C is the limiting factor in the thermal response time thermally conductive epoxy. This ensures that the TMP35/TMP36/ C of the sensor and can be represented by a single-pole RC time TMP37 die temperature is not affected by the surrounding air constant response. Figure 17 and Figure 19 show the thermal temperature. Because plastic IC packaging technology is used, response time of the TMP35/TMP36/TMP37 sensors under excessive mechanical stress should be avoided when fastening the various conditions. The thermal time constant of a temperature device with a clamp or a screw-on heat tab. Thermally conductive sensor is defined as the time required for the sensor to reach epoxy or glue, which must be electrically nonconductive, is 63.2% of the final value for a step change in the temperature. recommended under typical mounting conditions.

DRIVING LONG CABLES OR HEAVY CAPACITIVE LOADS Although the TMP35/TMP36/TMP37 temperature sensors can drive capacitive loads up to 10,000 pF without oscillation, output voltage transient response times can be improved by using a small resistor in series with the output of the temperature sensor, as shown in Figure 35. As an added benefit, this resistor forms a low-pass filter with the cable capacitance, which helps to reduce bandwidth noise. Because the temperature sensor is likely to be used in environments where the ambient noise level can be very high, this resistor helps to prevent rectification by the devices of the high frequency noise.
