Safety is a key feature in home appliance designs. The IEC 60730 safety standard defines the test and diagnostic methods to ensure safe operation of electronic controls in home appliances.
To design safe and reliable household appliances that target IEC 60730 Class B compliance, we offer a broad portfolio of IEC 60730 functional safety ready dsPIC33E Digital Signal Controllers (DSCs) that can serve as the main controller to implement:
To simplify the design and certification of safety-critical household appliances, dsPIC33E DSCs encompas the hardware safety features and a comprehensive safety ecosystem.
The Class B library contains the diagnostic tests necessary to develop your end product and get the IEC 60730 standard certification. This library for the dsPIC33E DSCs is verified by VDE and certified by UL. You can download it for free and use it with our dsPIC33E DSCs. The Class B safety routines can be called periodically at startup or runtime to test:
We recommend using the Class B library with the certified MPLAB XC16 functional safety compiler.
AN1778 describes the Class B Safety Software Library routines that are developed in accordance with the IEC 60730 Class B standard. The application note describes:
In addition, the application note outlines techniques beyond Class B safety routines to test components such as external communication, timing, I/Os and analog multiplexer.
dsPIC33E DSCs can be used in a variety of applications targeting household appliances. Use the links below to learn about the key features these devices offer for general embedded, motor control and digital power designs.
When you are designing functional safety applications, using development tools that meet the requirements of safety standards can make creating compliant systems easier. To help you with implementing system-level functional safety in your applications, our MPLAB XC16 C compiler is TÜV SÜD certified for IEC 60730 safety standards. We also provide the complete certification packages for our MPLAB development tools ecosystem to help your projects qualify for the certification.
