Dealing with inrush currents in distribution transformers

Among the subtleties associated with distribution switchgear configuration, inrush current is a necessary evil which must be taken into consideration. It is the source of much frustration for field operators and SCADA control teams; when issuing a close command on an open breaker results in an immediate trip. Was it genuine fault? Is it risky […]

Smart-card interface

The DS8023 is a low-cost, smart-card interface IC for use in financial terminals, consumer set-top boxes, and other smart-card reader products. This device features the industry’s lowest stop-mode current, significantly reducing the amount of current consumed by the application. It provides a robust communication interface that translates I/O signals to smart-card levels and protects the […]
