SIEMENS SAE 0530; SAE 0531; SAE 0532 Functional Description Programming of Delay Times On input N there is a Schmitt trigger for detecting the clock signal plus rectifier and Z-diodes for deriving the operating voltage from the clock source (e.g. line voltage). The clock signal is applied to a basic divider (1:50 or 1:60) to generate a seconds clock from the line frequency, three switchable dividers (1:60, 1:10 and 1:3) for setting the basic timing and six 1:2 dividers with open-collector outputs. The set time will have expired when the appropriate outputs go high. The basic-timing dividers are controlled by the wiring of inputs A, B and C (and CO)* At 50- or 60-Hz clock frequency it is possible to set the following basic timing: Changeover (SAE 0532 G) co [Line Frequency L 60 Hz H 50 Hz TimingRange (A |B |C _ |Basic Timing Max.

The flipflops are connected to pins D, E, F, G, H and | so that the latter adopt a certain value, i.e. 1, 2, 4, 8, 16 and 32. The required delay time on output T (triac driver) is calculated by the following equation: delay = basic timing ~ value D through I. This time is then produced by connecting the appropriate pins D through ! to pin R (reset). If a number of the outputs D through | are connected to R, the times add up. * Information in parentheses apply to SAE 0532 G. Semiconductor Group 474

Types of Delay The circuit permits two different functions, which are selected on pin FC (function changeover). The two functions can be retriggered while the timing is running 1. Turn-on interval DIN 46120 (figure 1) The triac connected to T turns on with the rising edge on the start input S and off when the set time has elapsed, and does this independently of the length of the start pulse. The effect of noise pulses on the start input is minimized by the dead times. 2. Dropout delay to DIN 46120 (figure 2) The triac turns on with the rising edge on S. The falling edge on S triggers the timing. The triac remains turned on until the set time has expired. FC [Function L Turn-ON interval H Dropout delay Semiconductor Group 475

SIEMENS SAE 0530; SAE 0531; SAE 0532 Start of Time Measurement (Figure 1, 2) The frequency divider (and thus the time measurement) is started — for the turn-on interval function (FC = L) with start input S = H by two negative edges on — for the dropout delay function (FC = H) with S = H during at least two negative edges on Nand then S = L by two more negative edges on N. New Start of Time Measurement and Counter Reset If, with the reset input R = L, the start input S is toggled (observing the condition: at least two negative edges on N), the time measurement is started again each time (retrigger function). When R =H and there are two negative edges on N, the counter is reset (reset function). This clocked control ensures a large degree of resistance to noise pulses that are coupled in. The reset function is also enabled by turning on the supply voltage, because the IC has a startup circuit. But this only takes effect if the preceding interruption of the supply voltage was long enough (in the region of a few ms). This avoids reset caused by interference on the supply voltage Output Stage The output stage is also controlled by S and R. The open-collector output T is enabled by S=H and disabled by R=H when there are two negative edges on N (and when the supply voltage is turned on). If start input S and reset input R are high at the same time, the output is enabled by the second negative edge and turned off again by the next positive edge (as long as R has not gone low in the meantime, as is usually the case). If the operating voltage drops below the operating limit of the circuit (approx. 3 V), the output is turned off for this duration. Semiconductor Group 477

SIEMENS SAE 0530; SAE 0531; SAE 0532 Triac Modes (Figure 3, 4) Different modes can be set for the enabled output by appropriate wiring of inputs TC (triac mode) and TS (triac synchronization): — Mode 1 (TC on Vs) (voltage synchronization) Output T is connected to the zero-voltage switch. T conducts when Vs — 1.3V < Vrs < Vs + 1.3 V; see Application Circuit 1 (operation of resistive loads). — Mode 2 (TC via Ce on GND or open) (current synchronization) Output T is connected to the zero-voltage switch via a monoflop. T issues a driving pulse, determined by Ce, when Vs - 1.3 V is no longer maintained on TS or Vs + 1.3 Vis exceeded; see Application Circuit 2. In the current-synchronization mode, gate-trigger current is supplied to T until the triac has fired. If the triac does not fire because the load current is too small, the trigger current flows permanently, which can lead to a drop in the supply voltage. In this way the current is reduced further and the supply voltage continues to drop until ultimately the output is turned off because the lower limit of the operating voltage is reached. The circuit remains in this state until T is finally disabled by the timing control. This process can be avoided by ensuring that the triac fires in all operating conditions. - Mode 3 (TC and TS on Vs) Output T conducts after the start pulse. This is used for any load in continuous driving of the triac (e.g. at low power levels) or if, instead of the triac, another load is operated; see Application Circuits 3, 4 and 5. Inputs N, S, R, FC, A, B, C (and CO)* have an internal pullup resistor, i.e. they are high if not wired. On start input S there are also clamping diodes to Vs and GND so that it is possible to start with external potential. Reset input R is usually connected to one or more of the open-collector outputs D through |, enabling cutout of the load and resetting of the counter when the set delay has elapsed. These outputs are turned off (R = H) in their basic state (after reset), conduct when the time measurement starts (R = L) and are turned off again (R = H) after the delay (see Figure 1 and 2). * Figures in parentheses apply to SAE 0532 G.

SIEMENS SAE 0530; SAE 0531; SAE 0532 Operation with Line Voltage A series resistor Rs and a charging capacitor Cen serve for line voltage supply. If a diode is connected in series with Rs (anode to N), the rms current consumption is halved. The series resistor may also be an RC network (see Application Circuit 6). Operation with DC Voltage This IC can also be operated with DC voltage or current (see Application Circuits 4 and 5). Useful Hints @ To obtain better noise immunity the pins D through | which are not connected are to be applied to GND. ec. If short-term line failures are to be compensated, Ci has to be accordingly higher. © Application Circuit 1 (voltage synchronization for resistive load) ‘An average /1s of 0.025 mA was inserted into the formula approximating Rsvw. As /1s « and Its- contain production deviations, utilizing the determined Rsvn requires certain tolerances to be taken into account for pulse length Z. @ Application Circuit 2 (current synchronization) LB In this circuit, an even shorter pulse length than determined for Z is sufficient to trigger the triac. This is possible by the trigger pulse being automatically repeated until the hold current is reached. Overdimensioning of Z for safety reasons is, therefore, not necessary. The disadvantage of multiple trigger pulses, however, is a somewhat larger interference band during the triggering. The noise band and/or the noise amplitude generated also depend on the amount of the gate trigger voltage necessary to trigger the triac after each current zero passage. That voltage is determined by the size of Rsvw and should not exceed 20 V. © Application Circuit 6 To limit the inrush current, Rss has to be = 0.2 Rs. Otherwise, the circuit might be de- stroyed. @ Application Circuit 9 If the delay is made selectable by using a mechanical switch, it should be noted that all inputs, because of the pullup, are high in an unwired condition. © Brief interruptions can be made ineffective by wiring with a capacitor. On S and R there is extra protection through the clocked control with a decision interval of one to two clock cycles. Semiconductor Group 479
