    How accurate is your battery fuel gauge? Part 1/2

    Part 1: Measurement and gauging accuracy A battery gauge, commonly called a gas or fuel gauge, obtains data from the battery to determine how much juice is left in it. Gauging accuracy should not be misconstrued for measurement accuracy of a gauge....

    Understanding battery charger features and charging topologies

    In my previous blog “ Selecting the right battery charger for industrial applications ”, we discussed the standalone vs. host controlled chargers and external vs integrated switching FETs. Now let’s take a look at different charging topologies. First of all, we have to better understand the battery charger features, Dynamic Power...

    Pass your power bank EMI test

    A key design challenge when designing a power bank is passing the electromagnetic interference (EMI) test. Electronics engineers often fear EMI test failures, and it would be a nightmare if the circuit failed the EMI test again and again. You...

    How to save power while shrinking your next mobile design

    Where did my charger go? My laptop is running low on battery again as I’m typing this. We are constantly struggling with battery life in today’s always-on connected world. Everything we use needs a longer battery life, but also needs a smaller battery. Impossible you say? Certainly not, but this trend of shrinking form factor while extending...

    Smart power banks support high voltage charging

    Power banks are becoming more and more popular as battery capacity outstrips the runtime of personal electronic devices like smartphones and tablets. High-performance CPUs, large sizes and high-resolution display panels also make runtimes shorter. This creates an demand for a fast-charging backup battery such as a power banks. Traditionally, a 5V...

    Use a dedicated parallel charger for cost-effective fast charging

    Today, system designers need to be much savvier about power management. Because of the ever-increasing number of functions and applications, there are greater demands on battery capacity. Users also demand shorter charge time, which requires faster charge currents. A single charger may not be able to support the high charge current needed, however...

    Another use for load switches: reverse battery protection

    Electronic devices are certainly ubiquitous today, with the average individual coming into contact with three to five handheld or mobile devices daily. All of these devices, however, need a portable power source or battery to keep the device running. But what happens when users insert batteries in reverse or connect wires with an unintentional negative...

    What does wireless power mean for industrial applications?

    Industrial application designers are just beginning to see the value of wireless power for their systems. Consider an electronic point-of-sale (ePOS) terminal. The flexibility of not being tethered to a system (by cables or wires) and not having to w...
