PUSHBUTTON INTERFACE
The LTC3101 includes a pushbutton interface that allows a single momentary pushbutton to control the sequenced power-up and power-down of all output rails in coordina- tion with an external microprocessor. In addition, three independent enable pins allow an unused DC/DC converter to be independently disabled and also provide the means to manually implement an alternate power-up sequence.

The LTC3101 can be enabled by either forcing PWRON high or by forcing PWRKEY low. In either case, the DC/DC converters (if enabled by their respective enable pin) will power up in the internally fixed default sequence: buck converter 1, buck converter 2, and finally the buck- boost converter. In the typical application, the power-on sequence is initiated when the PWRKEY is driven low by an external momentary pushbutton. Once the microproces- sor is powered up it must assert PWRON high before the pushbutton is released, thereby forcing the LTC3101 to

remain enabled. Power-down is usually accomplished by

Interoperability Dependencies in the Internet of Things (IoT)

Abstract:  As business capabilities continue to develop and evolve, our dependencies on technology continue to scale while diminishing our ability to operate in its absence. Security is often an afterthought or oversight in technology design and development, resulting in complex redesign post-process. As we embrace the "Internet of Things" (IoT), we must also embrace the interoperability dependencies of adjacent, independent technologies, policies and laws, which will drive the IoT into the foreseeable future. During this talk, Don Ritzman, Chief Executive Officer; and Antonio A. Rucci, Chief Security Officer, Ghost Systems, LLC, Reno, NV, will address high level strategy and technologies whic
