Voltage Monitoring  
Automatic Retriggering  
As the voltage is built up, uncontrolled output pulses are  
avoided by internal voltage monitoring. Apart from that  
all the latches in the circuit (phase control, load limit  
regulation) are reset and the soft-start capacitor is short  
circuited. This guarantees a specified start-up behavior  
each time the supply voltage is switched on or after short  
interruptions of the mains supply. Soft-start is initiated  
after the supply voltage has been built up. This behavior  
The current-detector circuit monitors the state of the triac  
after triggering by measuring the voltage drop at the triac  
gate. A current flow through the triac is recognized, when  
the voltage drop exceeds a threshold level of typ. 40 mV.  
If the triac is quenched within the relevant half-wave after  
triggering; for example owing to low load currents before  
or after the zero crossing of current wave or; for commu-  
tator motors, owing to brush lifters. Then the automatic  
retriggering circuit ensures immediate retriggering, if

a gentle start-up for the motor and  
automatically ensures the optimum run-up time.

Avoiding triggering due to inductive load.  
In the case of inductive load operation the current  
synchronization ensures that in the new half wave no  
pulse is enabled as long as there is a current available  
from the previous half-wave, which flows from the  
opposite polarity to the actual supply voltage.

Figure 3. Suppression of automatic retriggering and mains  
voltage compensation  
A special feature of the IC is the realization of current  
synchronization. The device evaluates the voltage at the  
pulse output between the gate and reference electrode of  
the triac. This results in saving separate current  
synchronization input with specified series resistance.  
A further feature of the IC is the selection between soft-  
start or load-current compensation. Soft-start is possible  
by connecting a capacitor between Pin 1 and Pin 4, see  
figure 7. In the case of load current compensation, Pin 1  
is directly connected with resistance R , which is used for  
6
sensing load current.  
Voltage Synchronization with Mains Voltage  
Compensation, Pin 7  
Load Current Detection, Pin 1  
The voltage detector synchronizes the reference ramp  
with the mains supply voltage. At the same time, the  
mains dependent input current at Pin 7 is shaped and rec-  
tified internally. This current activates the automatic  
retriggering and at the same time is available at Pin 3 (see  
figure 8). By suitable dimensioning, it is possible to attain  
the specified compensation effect. Automatic  
retriggering and mains voltage compensation are not  
The circuit continuously measures the load current as a  
voltage drop at resistance R . The evaluation and use of  
6
both half waves results in a quick reaction to load current  
change. Due to voltage at resistance R , there is an  
6
increase of input current at Pin 1. This current increase  
controls the internal current source, whose positive  
current values is available at Pin 3 (see figure 9). The  
output current generated at Pin 3 contains the difference  
from the load-current detection and from the  
mains-voltage compensation (see figure 1).

defines the width of the zero voltage cross-over pulse,  
synchronization current, and hence the mains supply  
voltage compensation current. If the mains voltage  
compensation and the automatic retriggering are not  
required, both functions can be suppressed by limiting  
The effective control voltage is the final current at Pin 3  
together with the desired value network. An increase of  
mains voltage causes the increase of control angle α. An  
increase of load current results in a decrease in the control  
angle. This avoids a decrease in revolution by increasing  
the load as well as the increase of revolution by the  
increment of mains supply voltage.

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.
