Abstract :
Unlike signal switching, power switches have significant minimum operational requirements for both voltage and current. These minimum requirements affect usage in test programs and self test approaches. This paper will discuss the considerations necessary when testing power switches or when using power switching in test programs. In addition, techniques will be described which can reduce or remove build up of deposits, improving switch operation.
