Scaling Power-Supply Slopes

Posted Jun 19, 2013 By Maxim

Abstract: This application note discusses designing power-on reset (POR) circuits for a wide range of voltage conditions. After reviewing why a POR typically fails, this application note covers the best ways to make the POR work safely, to test the POR, and to implement a design strategy—all with an eye on making the POR function more reliably.
Create a 1-Wire Master with Xilinx PicoBlaze

Posted Jun 18, 2013 By Maxim

Abstract: Designers who must interface 1-Wire® temperature sensors with Xilinx field-programmable gate arrays (FPGAs) can use this reference design to drive a DS28EA00 1-Wire slave device. The downloadable software mentioned in this document can also be used as a starting point to connect other 1-Wire slave devices. The system implements a 1-Wire master connected to a UART and outputs...
Enhancing ESD Protection

Posted Jun 18, 2013 By Littelfuse

In the previous white paper, Selecting an Appropriate ESD Device, we focused solely on the idea that an ESD device’s main goal was to provide the lowest resistance shunt path to GND. And from that idea, we gave the board designer a method from which he/she could calculate the effective resistance of a protection device during an ESD transient. This resistance, or dynamic resistance, could...
Google’s Internet Balloon Network

Posted Jun 18, 2013 By Tom Lombardo

Google wants to bring wireless internet service to the whole world through its airborne Loon network. The pilot project got off the ground on June 15th, launching from Christchurch New Zealand.

A Loon is a helium-filled mylar balloon floating about 20 km (12 mi) above the Earth’s surface, carrying an internet router and associated gear. Each unit can provide internet access to a 40…
Renewable Storage at the Edge of the Grid

Posted Jun 18, 2013 By Nicholas Abi-Samra

Over the last three years, utility customers have observed or been impacted by weather-related, long term outages that have attracted increasing attention to the concept of reliability and resiliency. The monetary impact of reliability has always been a challenge to quantify for the typical, small end-user; often being thought of simply as inconveniences, rather than an impactful disruption to...
Advances in WLED/RGB LED Drivers

Posted Jun 17, 2013 By Allegro MicroSystems

The increasing use of LEDs for backlighting TFT LCD panels in automotive navigation/infotainment, computer monitors, LCD TVs, and notebook computer screens, has generated a demand for optimization of power regulation techniques for those LEDs. The potential savings in system design and increase in overall performance can have a growing impact on customer acceptance as these applications spread...
BeagleBone Black - Unleashing Innovation

Posted Jun 15, 2013 By Texas Instruments

BeagleBoard.org was founded to give developers, hobbyists and students robust open-source hardware development platforms so they could quickly and cost effectively assemble systems by leveraging the many advantages of the open-source ecosystem. BeagleBoard, BeagleBoard-xM, BeagleBone and now BeagleBone Black provide flexible and expandable opensource platforms for all electronic artists – from...
Cause of Flicker in LCD Screens

Posted Jun 15, 2013 By Intersil

When comparing CRT to LCD screens, one of the most popular differences is the issue of flicker. It is a common assumption that CRT screens flicker while LCD screens do not. In truth, both screens have some amount of flicker. The mechanisms are different and methods for correction have varying amounts of success. This appnote presents the cause of flicker in LCD screens and offers a solution...
