Adding USB Type-C with USB Power Delivery to Battery-powered Applications

A USB Type-C port with USB Power Delivery (PD) is becoming the standard port for charging single- and multi-cell battery-powered devices. Applications such as wireless speakers, power banks and power tools have been transitioning from proprietary charging ports, legacy USB ports and barrel-jack ports to a standardised USB PD port. USB PD offers a universal alternative for fast and convenient charging, removing the need for users to carry around several adapters or cables with them – helping design engineers create smaller applications with faster charging and fewer components.

96-Channel Bidirectional Digital Input Module Reference Design for PLC

This reference design is a compact implementation of 96 isolated digital input channels using the ISO1212, an isolated digital input receiver.
