    SimpleLink™ MCU SDKs: What is an SDK plug-in?

    One of the challenges in systems development is expanding beyond the capabilities of your selected microcontroller (MCU). This expansion could include connecting to sensors or actuators to interface with the environment, or connecting to additional controllers or radios for more flexibility or connectivity options. Developing drivers for these external...

    Why a wide VIN DC/DC converter is a good fit for high-cell-count battery-powered drones

    More and more drone applications require high-cell-count battery packs to support longer flying distances and flight times. For example, consider a 14-series lithium-ion (Li-ion) battery pack architecture where the working voltage is 50V to 60V. When designing a DC/DC power supply for such a system, one of the challenges is how to select the maximum...

    “Trust, but verify” SPICE model accuracy, part 5: input offset voltage and open-loop gain

    Previous installments of this blog post series discussed the need to verify SPICE model accuracy and how to measure common-mode rejection ratio (CMRR), offset voltage versus common-mode voltage (Vos vs. Vcm), slew rate (SR) and open-loop output impedance (Zo). In part 5, I’ll explain how to verify two of the most impactful specs of precision operational...

    FPGA power made simple: design steps

    Over the last three installments of this series, I have gone over some basic design considerations for creating a power supply for field-programmable gate arrays (FPGAs). Now that you have determined the power requirements and identified some necessary feature and performance specifications, you are ready to pick parts! One way to simplify FPGA power...

    Use Ultrasonic sensing for graceful robots

    We’re not far from the day when robots perform many of the tasks done by humans today. We already have robotic vacuums cleaning our homes and robotic mowers cutting the grass in our yards. On factory floors, robots are building many of the products we use, from toothbrushes to cars. Robots are serving food in China and Japan, while drones are...

    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...
