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 […]
Low-noise dc/dc switching regulators host integrated ferrite-bead compensation
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, […]
And the LEAP Gold for Power Electronics goes to…Cornell Dubilier
The winners of the 2020 LEAP Awards (Leadership in Engineering Achievement Program) were announced last week in a digital ceremony, with products across 12 categories, including embedded computing, power electronics, and test and measurement. Critical to LEAP’s success is the involvement of the engineering community. No one at WTWH Media selected the winners. Instead, our […]
Higher contrast, better resolution: Automotive display full-array local dimming
By Logan Cummins, Infotainment Systems Engineer, Texas Instruments A local dimming backlight technology individually adjusts LEDs in an LCD panel to save power and improve contrast ratios in automotive displays. Compared to globally dimmed displays and organic LEDs (OLEDs), local dimming with LEDs is a more practical design choice because it can withstand the extreme […]
A better automotive display from pixel to picture with local dimming
By Logan Cummins, Infotainment Systems Engineer, Texas Instruments Automotive specifications and environmental conditions have caused the automotive display market to lag behind the consumer display industry in contrast ratio, black levels, resolution, curvature, and form factor. Automakers try to differentiate their infotainment human-machine interface (HMI) displays and catch up to the technological advances now common […]
DC-DC buck-boost converter extends lifespan of battery-powered industrial and personal electronics applications
Texas Instruments introduced the industry’s first DC/DC buck-boost converter to combine programmable input current limit and integrated dynamic voltage scaling to extend battery life by at least 50%. The TPS63900 maintains the industry’s lowest quiescent current (IQ), 75 nA, with 92% efficiency at 10 µA and delivers up to three times more output current than […]
Hall-effect current sensors first with zero drift
Texas Instruments introduced the industry’s first zero-drift Hall-effect current sensors. The TMCS1100 and TMCS1101 enable the lowest drift and highest accuracy over time and temperature while providing reliable 3-kVrms isolation, which is especially important for AC or DC high-voltage systems such as industrial motor drives, solar inverters, energy-storage equipment and power supplies. Ongoing demand for higher […]
Buck-boost charger ICs for USB Type-C and USB Power Delivery ports hit 97% charging efficiency
Texas Instruments introduced the industry’s smallest buck-boost battery charger integrated circuits, which integrate power-path management for maximum power density and universal and fast charging at up to 97% efficiency. The BQ25790 and BQ25792 support efficient charging and 10 times lower quiescent current through USB Type-C and USB Power Delivery (PD) ports in small personal electronics, […]
DC-dc converter ICs can be stacked to deliver 160 A
Texas Instruments introduced a new 40-A SWIFTTM DC/DC buck converter, offering first-of-its-kind stackability of up to four integrated circuits (ICs). The TPS546D24A PMBus buck converter can deliver up to 160 A of output current at an 85°C ambient temperature – four times more current than competing power ICs. The TPS546D24A has the highest efficiency of any 40-A DC/DC converter, […]
