... Figure 13. Detailed Block Diagram TEMPERATURE HYSTERESIS The temperature hysteresis is the number of degrees beyond the original setpoint temperature that must be sensed by the TMP01 before the setpoint comparator is reset and the output disabled. Figure 14 shows the hysteresis profile. The hysteresis is programmed by the user by setting a specific load on the reference voltage output VREF ...

... Thus, allow sufficient SETHIGH VREF time for the device to reach the final temperature. The typical thermal time constant for the plastic package is approximately 140 seconds in still air. Therefore, to reach the final temperature accuracy within 1%, for a temperature change of 60 degrees, a settling time of 5 time constants minutes, is necessary ...

... THERMAL RESPONSE TIME The time required for a temperature sensor to settle to a speci- fied accuracy is a function of the thermal mass of the sensor, and the thermal conductivity between the sensor and the object being sensed ...

... OUTPUTS In many temperature sensing and control applications, some type of switching is required. Whether turn on a heater when the temperature goes below a minimum value or to turn off a motor that is overheating, the open-collector outputs OVER and UNDER can be used. For the majority of applications, the switches used need to handle large currents on the order and above ...

... Figure 21. Controlling the 2N6073A Triac HIGH CURRENT SWITCHING Internal dissipation due to large loads on the TMP01 outputs causes some temperature error due to self-heating. External transistors remove the load from the TMP01, so that virtually no power is dissipated in the internal transistors and no self- heating occurs. Figure 22 through Figure 24 show a few examples using external transistors ...

... BUFFERING THE TEMPERATURE OUTPUT PIN The VPTAT sensor output is a low impedance dc output voltage with a 5 mV/K temperature coefficient, that is useful in multiple measurement and control applications. In many applications, this voltage needs to be transmitted to a central location for processing. The buffered VPTAT voltage output is capable of 500 μ ...

... TMP01 The current is proportional to the voltage on the VPTAT output, and is calibrated temperature of −40° for +85°C. The main equation governing the operation of this circuit gives the current as a function of VPTAT ⎛ × × 1 VPTAT R 5 VREF = − ⎜ I OUT + ⎝ The resulting temperature coefficient of the output current is 128 μ ...

... This can be useful in sensitive equipment calibrated to work over a limited temper- ature range. R1, R2, and R3 in Figure 30 are chosen to give a temperature range of 10°C around room temperature (25°C). Thus, if the temperature in the equipment falls below 15°C or rises above 35° ...

... T = 0.0°C) OUT conversion to the Fahrenheit scale. Using the circuit in Figure 32, a temperature of 0.0°F gives an output of 0. room temp- erature (70°F), the output voltage is 700 mV. A −40°C to +85°C operating range translates into −40°F to +185°F. The errors are essentially the same as for the circuit in Figure 31 ...
