Rev. A1, 29-May-96 6 (20) Design Hints Practical trials are normally needed for the exact determination of the values of the relevant components in the load limiting. To make this evaluation easier, the following table shows the effect of the circuitry on the important parameters of the load limiting and summarises the general tendencies. Parameters Component affected R 10 R 9 C 9 Pmax increases decreases n.e. Pmin increases decreases n.e. Pmax / min increases n.e. n.e. td n.e. decreases increases tr n.e. increases increases Pmax – maximum continuous power dissipation P 1 = f(n) n /C0048 0 Pmin – power dissipation with no rotation P 1 = f(n) n = 0 td – operation delay time tr – recovery time n.e – no effect Pulse Output Stage The pulse output stage is short circuit protected and can typically deliver currents of 125 mA. For the design of smaller triggering currents, the function I GT = f(RGT ) has been given in the data sheets in the appendix. Automatic Retriggering The variable automatic retriggering prevents half cycles without current flow, even if the triac is turned off earlier e.g. due to a collector which is not exactly centered (brush lifter) or in the event of unsuccessful triggering. If it is necessary, another triggering pulse is generated after a time lapse which is determined by the repetition rate set by resistance between Pin 5 and Pin 3 (R 5-3). With the maximum repetition rate (Pin 5 directly connected to Pin 3), the next attempt to trigger comes after a pause of 4.5 t p and this is repeated until either the triac fires or the half-cycle finishes. If Pin 5 is connected, then only one trigger pulse per half-cycle is generated. Because the value of R 5-3 determines the charging current of C2, any repetition rate set using R5-3 is only valid for a fixed value of C2. General Hints and Explanation of Terms To ensure safe and trouble-free operation, the following points should be taken into consideration when circuits are being constructed or in the design of printed circuit boards. – The connecting lines from C 2 to Pin 7 and Pin 2 should be as short as possible: The connection to Pin 2 should not carry any additional high current such as the load current. When selecting C 2, a low temperature coefficient is desirable. – The common (earth) connections of the set-point generator, the tacho-generator and the final interference suppression capacitor C 4 of the f/V converter should not carry load current. – The tacho-generator should be mounted without influence by strong stray fields from the motor. – The connections from R10 and C5 should be as short as possible. To achieve a high noise immunity, a maximum ramp voltage of 6 V should be used. The typical resistance R/C0246 can be calculated from I/C0246 as follows: R /C0246(k/C0087) /C0043T(ms) /C00321.13(V)/C0032103 C /C0324nF) /C00326(V) T = Period duration for mains frequency (10 ms at 50 Hz) C /C0246 = Ramp capacitor, max. ramp voltage 6 V and constant voltage drop at R/C0246 = 1.13 V . A 10% lower value of R/C0246 (under worst case conditions) is recommended.

Rev. A1, 29-May-96 19 (20) The circuit is designed as a speed control on the reflection-coupled principle with 4 periods per revolution and a max. speed of 30.000 rpm. The separation of the coupler from the rotating aperture should be 1 mm approximately. In this experimental circuit, the power supply for the coupler was provided externally because of the relatively high current consumption. Instructions for adjusting: /C0068In the initial adjustment of the phase-control circuit, R 2 should be adjusted so that when R14 = 0 and R31 are in min. position, the motor just turns. /C0068The speed can now be adjusted as desired by means of R 31 between the limits determined by R13 and R14. /C0068The switch-off power of the limit load control can be set by R9. The lower R9, the higher the switch-off power. Dimensions in mm 94 8877 94 8875

Rev. A1, 29-May-96 20 (20) 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.
