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

Current Synchronization, Pin 8

Current synchronization fulfils two functions:

*Monitoring the current flow after triggering.

In case the triac extinguishes again or it does not switch

on, automatic triggering is activated as long as

triggering is successful.

U2008B

BZX55

C6V2

*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

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

both half waves results in a quick reaction to load-current

change. Due to voltage at resistance R , there is an

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.
