Application note

Multiplexed diagnostics of AC switches using two STCC08s

Introduction
The aim of this application note is to present opportunities to reduce the number of input
pins used on a microcontroller unit (MCU) to diagnose failures of several AC switches with
the STCC08. This document deals with the multiplexed diagnostics of two STCC08 and
gives technical recommendations on the implementation of this solution.

STCC08 overview
The STCC08 has been designed to improve home appliance safety. This new device can
