Abstract

Motor drives, white goods, appliances, and other equipment can become unsafe to operate if one of their components fail. These equipments are subject to the testing and qualification requirements of the International Electrotechnical Commission (IEC). Specifically, the IEC 60730-1 “Automatic electrical controls for household and similar use” safety standard. Similar practices are followed in the United States leveraging UL 1998 “Safety Software in Programmable Components.”

The aspects most relevant to microcontrollers (MCUs) are IEC 60730 Annex H and UL 1998 Annex A.2, which detail the diagnostic test requirements to support safe function of home appliances.

This document provides a high-level overview of these specifications as applied to an MCU and describes how C2000™ functional safety features can be leveraged to meet the diagnostic test requirements.
