    How to avoid the pain of a discharged device

    Frustration caused by a dead mobile device battery is not limited to adults with phones. Children too young to read can transform from charming angels to noisy demons when their tablet battery dies. This can be especially painful when it occurs during a long car ride. I have seen this happen, and recommend taking all reasonable steps to avoid it...

    Understanding the embedded USB2 (eUSB2) standard

    What is eUSB2? As applications like smartphones and tablets continue to pack more and more components into smaller form factors, it’s essential that interfaces shrink as well. However, the continued shrinking of system-on-chip (SoC) node size has led to a thinner gate oxide that can only support lower voltages. For devices relying on USB 2...

    Roll with the design punches and overcome power-sequencing challenges

    As boxer Mike Tyson once said, “Everybody has a plan until they get punched in the mouth.” Good boxers thrive when they can successfully throw their opponents off their game plan. Great boxers, however, are willing to get punched in the mouth and improvise until they can get back to their winning formula. Similarly, system designers must...
