Automatic Retriggering
Voltage Monitoring
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.
When the voltage is built up, uncontrolled output pulses
are avoided by internal voltage monitoring. Apart from
that, all 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
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), the automatic
retriggering circuit ensures immediate retriggering, if

*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 4. 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 8. 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 9). 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 11). The
output current generated at Pin 3 contains the difference
from the load-current detection and from the
mains-voltage compensation (see figure 9).

pulse, synchronization current, and hence the mains sup-
ply 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 Atmel Germany 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.
Atmel Germany GmbH 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.
Atmel Germany GmbH 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 Atmel Wireless & Microcontrollers products for any unintended
or unauthorized application, the buyer shall indemnify Atmel Wireless & Microcontrollers 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.
