How to gauge LED flicker

May 11, 2022 By Lee Teschler Leave a Comment

LED flicker

A few years ago, back when ordinary LED bulbs still sold for north of $10 a piece, there was a great brouhaha about LED light flicker. Light flicker can certainly be dangerous. Sufficiently intense flicker at between 3 and 70 Hz can cause epileptic seizure in a small percentage of the population. And flicker that […]

Relays designed for higher reliability in isolated high-voltage environments

May 10, 2022 By Aimee Kalnoskas Leave a Comment

Building on more than two decades of experience developing new isolation manufacturing technologies and integrated circuits (ICs) for high-voltage systems, Texas Instruments introduced new portfolio of solid-state relays, including automotive-qualified isolated drivers and switches, that deliver industry-leading reliability to help make electric vehicles (EVs) safer. The new isolated solid-state relays also provide the smallest solution […]

Buck/boost converter boasts super-low quiescent current, targets battery powered apps

November 5, 2021 By Redding Traiger Leave a Comment

Texas Instruments introduced a new bidirectional buck/boost converter with an ultra-low quiescent current (IQ) of 60 nA – one-third the IQ of competing boost converters. The TPS61094 buck/boost converter integrates a buck mode for supercapacitor charging while providing ultra-low IQ, enabling engineers to extend battery life by as much as 20% when compared to commonly used hybrid-layer […]

1.5 W, isolated dc-dc bias-supply module boasts small size

September 29, 2021 By Aimee Kalnoskas Leave a Comment

Texas Instruments introduced the industry’s smallest and most accurate 1.5-W isolated dc-dc bias-supply module. The UCC14240-Q1 uses a proprietary integrated transformer technology to enable designers to cut their power solution size in half for use in high-voltage environments such as electric vehicles (EVs), hybrid EVs, motor-drive systems and grid-tied inverters. With the accelerating growth of […]

Brushless BLDC motor drivers enables engineers to spin motor in less than 10 minutes

September 9, 2021 By Redding Traiger Leave a Comment

Texas Instruments introduced the industry’s first 70-W brushless DC (BLDC) motor drivers to provide code-free, sensorless trapezoidal, and field-oriented control (FOC). The devices enable engineers to spin a BLDC motor in less than 10 minutes – eliminating months of design time for engineers designing a wide variety of industrial systems such as major and small […]

Overcoming stepper motor design challenges in 3D printers

April 28, 2021 By Aimee Kalnoskas Leave a Comment

By Dipankar Mitra, System Engineer, Texas Instruments 3D printing is a fast-emerging market with significant growth potential. 3D printers create three-dimensional objects, with complex shapes and geometries, through the successive deposition of materials directly from a computer-aided design model. The agriculture, health care, automotive, locomotive, and aviation industries are some of the first adopters of […]

Next-gen BMS goes wireless, with proprietary protocol and functional safety compliance

January 7, 2021 By Aimee Kalnoskas Leave a Comment

Because today’s battery management systems (BMS) are wired, the common source of cable failures – wire harnesses and connectors – becomes a warranty and functional safety issue. With the launch of a wireless BMS that features the first independently assessed functional safety concept, Texas Instruments hopes to revolutionize electric vehicle (EV) BMS. By removing the […]

650 V automotive GaN FETs integrate 2.2. MHz gate driver, reduce onboard charger size

November 9, 2020 By Aimee Kalnoskas Leave a Comment

Vehicle electrification is transforming the automotive industry, and consumers are increasingly demanding vehicles that can charge faster and drive farther. As a result, engineers are being challenged to design compact, lightweight automotive systems without compromising vehicle performance. Texas Instruments’ new LMG3522R030-Q1 and LMG3525R030-Q1 650-V automotive GaN FETs for automotive and industrial applications are designed to […]

Low-noise dc/dc switching regulators host integrated ferrite-bead compensation

October 22, 2020 By Redding Traiger Leave a Comment

Texas Instruments introduced a new family of low-noise DC/DC switching regulators with integrated ferrite-bead compensation. The TPS62912 and TPS62913 offer low noise of 20 µVRMS for frequencies ranging from 100 Hz to 100 kHz and ultra-low output-voltage ripple of 10 µVRMS, giving engineers the ability to remove one or more low-dropout regulators (LDOs) from their designs, […]
