ELECTRONICS: Maxim Integrated Products introduces the MAX5969A/MAX5969B, IEEE(R) 802.3af/at-compliant interface controllers for PoE+ PDs (powered devices). These devices meet all IEEE 802.3at specifications and are backwards compatible with the IEEE 802.3af standard. These controllers can withstand transient voltage spikes up to 100V (abs maximum) without the aid of external components. Additionally, integrated wall-adapter detection circuitry enables the seamless switchover from PoE power to wall power, thus simplifying PD backup-power designs. The MAX5969A/MAX5969B are well suited for high-power applications such as IP phones, wireless LAN access points, IP security cameras, and RFID readers.
These PD interface controllers provide the PD with detection and classification signatures and integrate an isolation power switch with inrush current control. During the inrush period, the devices limit the current to less than 180mA before switching to a higher current limit (720mA to 880mA) when the isolation power MOSFET is fully enhanced.
The MAX5969A/MAX5969B are available in a 10-pin TDFN-EP package and are fully specified over the -40C to +85Cextended temperature range. Prices start at $1.21.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
