Texas Instruments introduced an ultra-low-power switching regulator with the industry’s lowest operating quiescent current (IQ) at 60 nA – 1/3 that of the nearest competitive device. The TPS62840 synchronous step-down converter delivers very high light-load efficiency of 80% at 1-µA load, which can enable designers to extend the battery life of their systems or use […]
Tiny current-sensing amps target overcurrent detection apps
Texas Instruments introduced the industry’s smallest current-sense amplifier in a leaded package and the smallest, most accurate comparators with an internal 1.2-V or 0.2-V reference. Offered in industry-leading package options, the INA185 current-sense amplifier, and open-drain TLV4021 and push-pull TLV4041 comparators enable engineers to design smaller, simpler and more integrated systems while maintaining high performance. […]
Charging electric vehicles, Part 2: The connections
Part 1 introduced some of the issues related to charging of electric vehicles. Part 2 continues with a look at the hardware (which also involves software, of course). Q: What about the electrical and physical connections? A: There are three connection situations, called “cases”: Case A has the charger connected to the AC mains, and […]
MCUs integrate, CAN FD, Ethernet, EtherCAT industrial communication protocols
Texas Instruments introduced new communications capabilities on its C2000 microcontrollers (MCUs). C2000 F2838x 32-bit MCUs enable designers to use a single chip to implement connectivity, including EtherCAT, Ethernet and Controller Area Network with Flexible Data Rate (CAN FD), in AC servo drives and other industrial systems. Systems with communication interfaces often require an external application-specific […]
Charging electric vehicles, Part 1: The numbers
It’s nice to envision that recharging an electric vehicle is as straightforward as filling up an internal combustion vehicle, but it’s not: there are multiple charging, power, and connector options as well as limitations. You’re driving your internal-combustion (IC) car, and the gauge indicates it’s time to get “gas” (of course, it’s actually gasoline). So […]
Automotive SBC helps designers add CAN FD without changing their microcontroller
Texas Instruments introduced an automotive system basis chip that is the industry’s first to integrate a controller and transceiver for Controller Area Network with Flexible Data Rate (CAN FD). Designed to meet the high-bandwidth and data-rate flexibility needs of in-vehicle networks, the TCAN4550-Q1 uses the Serial Peripheral Interface (SPI) bus of almost any microcontroller to […]
GaN power devices, Part 2: Application
Part 1 of this FAQ explored the basics of GaN switching transistors at the device and physics level. This part will look at driving and applying GaN devices. Q: What do I need to know to use a GaN device? A: There are three functional blocks associated with power switching: the power-device driver, the power […]
Fast 12-bit ADC features 8-GHz bandwidth, 10.4-GS/sec sampling rate
Texas Instruments today introduced a new ultra-high-speed analog-to-digital converter (ADC) with the industry’s widest bandwidth, fastest sampling rate and lowest power consumption. The ADC12DJ5200RF helps engineers achieve high measurement accuracy for 5G testing applications and oscilloscopes, and direct X-band sampling for emerging technologies in radar, microwave, and mmWave. “In general, what we are doing is […]
GaN power devices, Part 1: Principles
Power devices based on gallium nitride (GaN) are rapidly becoming a viable, higher-performance alternative to silicon MOSFETs due to their higher efficiency and other favorable attributes. In recent years, discrete power-switching and power-handling devices based on gallium nitride (GaN) material have become practical and available, and these devices are now found in many power supplies […]
Battery management system reference design boosts EV range
Texas Instruments introduced fully tested reference designs for battery management and traction inverter systems, along with new analog circuits with advanced monitoring and protection features to help reduce carbon dioxide emissions and enable hybrid electric vehicles and electric vehicles (HEV/EVs) to drive farther and longer. Scalable across six to 96-series cell supervision circuits, TI’s new battery […]
