    Gas gauging solutions for Li-ion batteries: Part 1

    Since it’s commercialization by Sony in 1991, lithium-ion (Li-ion) batteries have been widely adopted in portable devices for consumer, industrial and medical markets. The Li-ion battery is now making its way into many more sectors, replacing existing primary (nonrechargeable) batteries and lead-acid batteries due to its high energy density. ...

    How is GaN reliability being measured for application relevance?

    A customer recently asked me a question about gallium nitride (GaN) reliability: “It seems that JEDEC (the Joint Electron Device Engineering Council) does not cover application conditions in the switching power world. Any GaN device we would use in an end product should go through such testing. In my opinion, JEDEC should incorporate these kinds...

    TI hails Senate passage of TPA-2015

    On May 22, the U.S. Senate passed the Bipartisan Trade Priorities and Accountability Act of 2015 (TPA-2015). “As a company that earns nearly 90 percent of its revenue from markets overseas, TI strongly supports TPA-2015,” said Paula Collins, vice president of worldwide government relations. The bill provides an essential framework...

    How to get started with current sense amplifiers – part 2

    In part 1 of this series , I discussed the concepts of low-side or high-side monitoring and current flow directionality. In this second installment, I will discuss “how” the current information is used. What do I mean when I say “how...

    Understanding MOSFET data sheets, Part 3 - Continuous current ratings

    The first thing to understand about MOSFET current ratings is they’re not real. Ok, so maybe a better way to put it is just that they are not measured the way that parameters like RDS(ON) and gate charge are determined, but rather, they are cal...

    Battery Terms Decoded: Part 3

    I went through many battery terms and acronyms in part 1 and part 2 of this blog series, but now let’s talk about the most common acronym related to lithium-ion (Li-Ion) battery fuel gauging: SOC. You may already know this as state of charge (not system on chip, which is also commonly used for certain semiconductors). When you look at your...

    Caution! Your ADC may be only as good as its power supply

    When it comes to the analog signal chain, everyone understands the importance of the input signal path. We design our systems to capture and preserve the integrity of signals of interest, while doing our best to block out or reduce interference. We pay careful attention to the selection of every component placed along the way…and then we just...

    How to spin your stepper motor more efficiently – Part 2

    In part 1 of this series, I provided a few key ideas: TI hearts stepper motors. Stepper motors can be power-hungry. Back electromotive force (EMF) will indicate the stepper-motor load. You can control the output current based on back EMF. This can help save some power. No talking about current regulation! So now that all of...

    Multi-dimensional inductive sensing

    The title of this blog sounds like an excerpt from a science fiction movie, but in reality, integrating multiple sensor analog front-ends (AFEs) into a single device is nothing new. Suppliers have been releasing duals and quads of just about every bu...

    TI LaunchPad + Energia enable rapid prototyping at campus build events

    Taking college campuses by storm, popular “hackathon” events have traditionally focused only on software development. However, as more students dream up new applications for the Internet of Things (IoT), they are discovering the need to incorporate hardware into their embedded system designs. Inspired by low cost, low power EVMs with add...

    Is your power supply smart enough to be cool

    OK. I know the title is really corny, but I think you’re really going to like this post if you give it a chance. We’ve all heard over and over about the great things intelligent power will bring to the power-supply industry. In many ways it has met or exceeded our expectations; however, in other ways it has also let us down. I can’t...
