About a month ago, I was made aware that Texas Instruments's WEBENCH Power Architect Design tool has been integrated into Newark's and Farnell's product pages. I experimented with it myself and I thought it was an interesting. So, I asked Texas Instruments to see if they would be interested in getting some feedback regarding the tool's use. They agreed and are offering for FREE their recent Power Supply design book (valued at $58.99) to 5 reviewers who are will to write a blog about their experi ...
Gallium-nitride (GaN) FETs are increasingly finding use as high power devices for power electronics systems. They can realize ultra-high power-density operation with low power loss due to high carrier mobility in the two dimensional electron gas (2DEG) channel. GaN FETs are a majority carrier device, therefore, the absence of reverse recovery charge creates a good match for high-voltage operation.   To learn more about how a GaN FET power stage can outperform Silicon MOSFETs, read the att ...
Back in October, we launched a giveaway contest for the "new" Texas Instruments' Fundamentals of Power Supply Design Book. To compete in the contest, all you had to do was write a blog on the topic of TI power supply design and post it in the Texas Instruments Group.   About the Fundamentals of Power Supply Design Book This well-written, superbly illustrated, and easy-to-read reference book was written by Bob Mammano, a power supply industry expert, who is considered the father of the Pu ...
Texas Instruments recently released a book on the Fundamentals of Power Supply Design. It 's written by Bob Mammano, a power supply industry expert who is considered the father of the Pulse Width Modulation (PWM) Controller. It's a interesting mix of power supply fundamentals along with a history of the power supply industry of which Texas Instruments has played an important part in developing.   It's written for the beginner as well as the expert, covering power supply basics such as volt ...
Isolators are devices that minimize direct current (DC) and unwanted transient currents between two systems or circuits, while allowing data and power transmission between the two. In most applications, in addition to allowing the system to function properly, isolators also act as a barrier against high voltage.   For example, in this motor drive system, the isolated insulated gate bipolar transistor (IGBT) gate drivers level shift low-voltage signals from the control module to IGBT gate-d ...
Millimeter wave (mmWave) is a special class of radar technology that uses short-wavelength electromagnetic waves. Radar systems transmit electromagnetic wave signals that objects in their path then reflect. By capturing the reflected signal, a radar system can determine the range, velocity and angle of the objects.   mmWave radars transmit signals with a wavelength that is in the millimeter range. This is considered a short wavelength in the electromagnetic spectrum and is one of the advan ...
Sending remote-location data, especially over long distances beyond the ranges of WiFi or Bluetooth, is a critical part of a long-range IoT design common to industrial, environmental or even agricultural applicants. Texas has produced a simple way to create a wireless gateway that hosts all of the information from the sensor nodes to simplify the collection of data. All you need is a  Beagle Bone Black paired with the WLINK8 BeagleBone Black wireless cape and the SimpleLink™ Sub-1 GHz ...
Improving the performance or bandwidth of industrial servo-drive applications like robotic assembly systems, factory automation machinery and material handling systems can make a real impact to your application.   At the heart of the matter of improving servo drive performance is the system’s current loop performance or torque response. The current loop is critical to the performance of the rest of the system depends. Even though several alternative architectures can provide a pathwa ...
What is FRAM? FRAM stands for ferroelectric random access memory. As a ferroelectric memory, it is not affected by magnetic fields as there is no ferrous material (iron) in the chip.   What are the benefits of FRAM? FRAM offers several advantages over other memory technologies such as flash, including faster write speeds, unified memory, low energy writes and there is no need for pre-erasing. These advantages directly translate into real function-level benefits in low-power applications ...
Current limit in an LDO is defined by establishing an upper boundary for the current supplied. Unlike a constant current source, LDOs supply current on demand but can also control the total power regulated. Current limiting is achieved through internal circuitry controlling the output stage transistors inside the LDO. Source: Texas Instruments   This is a classic current-limit circuit for an LDO and is commonly referred to as a “brick-wall” current limit due to its abrupt c ...
A smart microphone integrates a traditional microphone with ultra-low-power digital signal processing technology for extracting command information from a human voice. When an application only needs a small set of commands, the DSP capability within the smart microphone can do all the computing locally without waking up the main system or connecting to a server. This capability is the key to interfacing with the human voice interface in smart appliances, TVs, robots and other digital assistants ...
There's a couple things you might not know about Bluetooth 5 worth knowing:   Data transfer rate up to 2Mbps Twice as fast is Bluetooth 4.2 and 5 times faster than Bluetooth 4.0 High-speed or long-range modes for increased flexibility   Because the data transfer rate can go as high as 2Mbps, you can develop applications using voice, audio, imaging, and data logging that were not previously an option using Bluetooth low energy.   To learn more, check out this article.   ...
What's so interesting about the DAC8775? Well let me tell you:   The DAC8775 is a quad-channel precision, fully integrated, 16-bit, digital-to-analog converter (DAC) with adaptive power management, and is designed to meet the requirements of industrial control applications.The adaptive power management circuit, when enabled, minimizes the power dissipation of the chip.   When programmed as a current output, the supply voltage on the current output driver is regulated between 4.5 V an ...
For anyone who has had to slug their way through technical documentation, let me tell you that it can be a difficult experience in learning patience. But sometimes you have to put in the time if it has good information that you need to do your job.   If not datasheets or user manuals, what other choices do you have to get the information you need, especially when a design project is nearing the deadline? Dust off those big thick engineering textbooks you bought (or took a loan to buy) when ...
Now that I have stirred up the community's interest in drone and quadcopter design from a recent Texas Instrument's Webinar, let me offer yo something else: a chance to win a free Cheerson CX-10A Remote Control Drone.     Just click here to enter. ...
