Zero-Voltage Switch with Adjustable Ramp
T2117
Description
The integrated circuit, T2117, is designed as a zero-
voltage switch in bipolar technology. It is used to control
resistive loads at mains by a triac in zero-crossing mode.
A ramp generator allows power control function by
period group control, whereas full-wave logic guarantees
that full mains cycles are used for load switching.
Features
D Direct supply from the mains
D Current consumption ≤ 0.5 mA
D Very few external components
D Full-wave drive – no DC current component in the
load circuit
D Negative output current pulse typ. 100 mA –
short-circuit protected
D Simple power control
D Ramp generator
D Reference voltage
Applications
D Full-wave power control
D Temperature regulation
D Power blinking switch

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.
