in the circuit, the divider and the control logic are reset. order to immediately make the entire function visible. in the ON state until the tracking time is over. load switching (see figure 4). set at Pin 11 (see figure 5). the range becomes temperature independent. Figure 4. Trigger condition, Pin 9 Figure 5. Trigger condition, Pin 10 signals at the inputs do not cause undesired triggering. load is switched off in order to avoid any intrinsic fault. Cosc2 should not be greater than 1/C0109F. they can be adapted to the respective requirements.

Rev. A1, 30-May-96 5 (9) RC Oscillator 1, Pin 12 The oscillator 1 with the following divider stage 1:1024 allows a very long and reproducible tracking time t t. The circuitry of Pin 12 for a certain tracking time tt can be calculated as follows: R osc1 [k/C0087]/C0043tt [s]/C0032103 1.6/C00321024 /C0032C osc1 [/C0109F] whereas Cosc1 should not be greater than 1/C0109F. Voltage Divider, Pin 1 Two freely connectable operational amplifiers, OP1 and OP2, are used to evaluate several sensor signals. The tap of a voltage divider between GND and V Ref with a voltage level of 0.6/C0032V Ref is available at Pin 1. The middle of the discriminator window is also at this value. Assuming that the output of one operational amplifier is connected at the trigger input, Pin 10 (window discriminator), the dc operating point of this operational amplifier can be adjusted without additional external resistors by connecting the input to Pin 1. This value is approximately in the center of the dynamic range of the OP.

Rev. A1, 30-May-96 9 (9) Ozone Depleting Substances Policy Statement It is the policy of TEMIC TELEFUNKEN microelectronic GmbH to 1. Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs). The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. TEMIC TELEFUNKEN microelectronic GmbH semiconductor division has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency (EPA) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively. TEMIC can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use TEMIC products for any unintended or unauthorized application, the buyer shall indemnify TEMIC against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
