By Durga Praveen G and Rakesh Panguloori, Texas Instruments There is unprecedented demand for highly available and redundant systems to offer the best user experience. For example, in communications, banking, and industrial automated systems, any amount of system downtime could potentially lead to lost customers. The implementation of a hot-swap circuit at the input of […]

How to gauge 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
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
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
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
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
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
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
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 […]
