    Industrial radar sensors need 77GHz

    Although specialized applications (primarily within the military) have used radar technology for sensing for nearly a century, simplification and size reductions through integration and higher operating frequencies have expanded the use of radar sensing to include automotive and industrial applications. In the past, radar technology was reserved for...

    “Peak current-mode control” in an LLC converter

    In 1978, when Cecil Deisch worked on a push-pull converter, he faced a problem of how to balance the flux in the transformer and keep the core from walking away into saturation caused by slightly asymmetrical pulse-width modulation (PWM) waveforms. He came up with a solution of adding an inner-current loop to the voltage loop and let the switch turn...

    Modern, sleek and durable touch on metal HMIs

    Many industrial and consumer electronic product designers use metal in their designs due to its modern look and durability. However, implementing human machine interfaces (HMIs) on metal surfaces is challenging, as it requires machining and cutting a...

    Seven things that only an analog engineer would understand

    I’m sure you’ve been asked at some point what you do for a living. For me, it is normally an odd conversation: Them: What do you do?Me: I work at Texas Instruments.Them: So you make the calculators!Me: No, actually I work in Analog.Them: ...

    Cycle scavenging on C2000™ MCUs, part 4: ADC post-processing blocks

    The idea of “cycle scavenging” is built into the DNA of C2000 microcontrollers (MCUs), which enables them to minimize latency at every stage of real-time control without compromising performance. In previous installments of this series , I looked at a number of features on C2000 MCUs, including zero-wait-state analog-to-digital converter...

    The D-CAP+™ Modulator: Evaluating the small-signal robustness

    In a previous Power House blog post , I introduced TI’s D-CAP+ multiphase regulator control topology and covered the basics of its architecture, steady-state operation and transient performance versus a competitor’s part. I also said something when listing some of the features of the D-CAP+ control topology that at first glance just seems...

    Real-time control meets real-time industrial communications development – part one

    In my previous blog post, “ EtherCAT and C2000™ MCUs – real-time communications meets real-time control ,” I discussed a design in the TI Designs reference design library to help ease hardware development of International Electrotechnical Commission (IEC) 61158-compliant EtherCAT slave nodes based on TI C2000 real-time control...

    Introduction to EV charging displays

    As more people own electric cars and plug-in hybrid electric vehicles (PHEVs), the electric vehicle service equipment (EVSE) infrastructure will need to support all of the extra battery-powered vehicles on the road. To address the quickly growing demand, EVSE components should be low cost and quick to set up. A charging station typically includes...

    Three ways DLP® technology can enable augmented reality experiences

    You put on your augmented reality (AR) headset and look up at the ceiling in your living room. At first, nothing looks out of the ordinary. Then a small piece of drywall seems to fall to the floor, followed by another, larger chunk. The 3D display in the headset makes it look convincing. Suddenly, the ceiling caves in and you are squinting into the...

    How to minimize undershoot when the pre-boost converter wakes up

    The start-stop system in hybrid electric vehicles (HEVs) helps reduce fuel consumption and emissions by stopping the engine during idling, but the battery voltage drops whenever the engine restarts. To provide the minimum required voltage to the loads during the battery voltage drop, pre-boost converters are widely used in automobiles. Table 1 shows...

    FPGA power made simple: sequencing

    I hope you enjoyed the last blog on rail requirements. Now we move on to sequencing, another important topic in field-programmable gate array (FPGA) power design. While powering the FPGA on and off, the power supplies need to turn on in a particular order. The exact sequencing series will vary, but typically the core rail is the first on and the first...

    How to choose a TVS diode for RS-232, RS-485 and CAN based on voltage ratings

    In many industrial and automotive applications, protecting the interface transceivers from all kinds of electrical overstress events is a major concern. Transient voltage suppressor (TVS) diodes are common devices for this purpose, since they can clamp the voltage spikes by generating a low-impedance current path. The electrical characteristics of...
