Quality: Integrated Circuits

Environmental Compliance

iWatt recognizes that the Earth is an irreplaceable asset, and that we must all actively participate in the preservation the environment and protection of human health. iWatt is a strong supporter of environmental protection activities in a technically and financially appropriate manner.

As a "Fabless Supplier" of power management Integrated Circuits, our products are manufactured at facilities not operated directly under iWatt control.  It is iWatt’s policy to develop supplier relationships only with companies who are committed to environmental preservation, and who comply fully with environmental laws, regulations, and industry environmental guidelines.  We continue to work with our subcontact partners to adopt advanced process technologies that will have ever decreasing impact on the environment, world-wide.

iWatt maintains current documented evidence and assurances from all material sources that our IC products fully comply with the requirements of:  RoHS, REACH-SVHC, and exceed industry requirements for Halide Free.

If your company requires analytical evidence to verify compliance of iWatt IC Products to the international standards governing Hazardous Substances; Visit http://edistribution.iwatt.com and register for access to the reports of interest.

 

RoHS: Restriction of Hazardous Substances

iWatt products are fully compliant with the EU Restriction of Hazardous Substances Directive (RoHS) 2002/95/EC. All iWatt Products are Halide Free, containing very low concentrations of Halogens [Chlorine, Bromine and Antimony], well below the internationally suggested limits. [Refer to Table A]

Working with our assembly subcontractors, iWatt selects and qualifies materials which have been verified [1] and are continually monitored [2] to be fully compliant to Directive 2002/95/EC.

The integrated circuit material supply industry is currently working to the common standard of hazardous substance identification, measurement, and limits established up by the EU Restriction of Hazardous Substances Directive, effective July 1, 2006, and subsequent EC material restrictions published since.

REACH:  Registration, Evaluation, Authorization and restriction of Chemicals

June 1, 2007 the EU established the REACH regulation for Registration, Evaluation, Authorization and Restriction of Chemicals.  It streamlines and improves the former legislative framework on chemicals of the European Union (EU).

The main aims of REACH are to improve the protection of human health and the environment from the risks that can be posed by chemicals, the promotion of alternative test methods, the free circulation of substances on the internal market and enhancing competitiveness and innovation.

REACH makes industry responsible for assessing and managing the risks posed by chemicals and providing appropriate safety information to their users.  In parallel, the European Union can take additional measures on highly dangerous substances, where there is a need for complementing action at EU level.

All manufacturers and importers of chemicals must identify and manage risks linked to the substances they manufacture and market.  For substances manufactured or imported in quantities of 1 tonne or more per year per company, manufacturers and importers need to demonstrate that they have appropriately done so by means of a registration dossier, which must be submitted to the European Chemicals Agency (ECHA).

REACH also foresees an authorization system aiming to ensure that substances of very high concern are properly controlled, and progressively replaced by suitable alternative substances or technologies where these are economically and technically viable.

In addition, EU authorities may impose restrictions on the manufacture, use or placing on the market of substances causing an unacceptable risk to human health or the environment.  The EU Member States are responsible for enforcing REACH through inspections as well as penalties in case of non-compliance.

Article 141 of the REACH Regulation provides the dates of entry into force and application of the REACH obligations and provisions.   

• June 1, 2007, the REACH Regulation entered into force and those provisions not mentioned in Article 141 (2) to (4) started to apply. 
  
• June 1, 2008 most of the main provisions started to apply. 
• June 1, 2009 Title VIII and Annex XVII on Restrictions are applied.
