... 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 TMP01 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 ...

... 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 will be reset and the output disabled. Figure 2 shows the hysteresis profile. The hysteresis is programmed by the user by setting a specific load on the refer- ence voltage output VREF ...

... This can account for some setpoint voltage error, equal to the change in bias current times the effective setpoint divider ladder resistance to ground. The thermal mass of the TMP01 package and the degree of ther- mal coupling to the surrounding circuitry are the largest factors in determining the rate of thermal settling, which ultimately determines the rate at which the desired temperature measure- ment accuracy may be reached ...

... As the contact power handling capability increases, so does the current needed for the coil. In some cases, an external driving transistor should be used to remove the current load on the TMP01 as explained in the next section. Power FETs are popular for handling a variety of high current dc loads ...

... R2. Note that the other amplifier in the dual OP290 is used to buffer the 2.5 V reference voltage of the TMP01 for an accurate, low drift LED bias level without affecting the programmed hysteresis current. A REF43 (a precision 2.5 V reference) provides an accurate bias level at the receiving end ...

... VPTAT 3 4 100k –15V 100k 1 VREF TMP01 6.49k 5 VPTAT 100k However, the gain from VPTAT to the output is two, so that 5 mV/K becomes 10 mV/°C. Thus, for a temperature of 80°C, the output voltage is 800 mV. Circuit errors will be due prima- rily to the inaccuracies of the resistor values. Using 1% resistors, the observed error was less than 10 mV, or 1° ...
