Texas Instruments introduced the newest addition to the TI Robotics System Learning Kit (TI-RSLK) family, the TI-RSLK MAX, a low-cost robotics kit and curriculum that is simple to build, code and test. Designed for the university classroom, the solderless assembly allows students to have their own fully functioning embedded system built in under 15 minutes. […]
Battery charger delivers termination current of 20 mA
Texas Instruments introduced a new switching battery charger integrated circuit (IC) that supports a termination current of 20 mA. Compared to competing devices, which typically support a termination current higher than 60 mA, TI’s BQ25619 enables 7% higher battery capacity and longer run time. The BQ25619 charger also delivers three-in-one boost converter integration and ultra-fast […]

Standard amplifier functions in HEV/EV battery management systems
by Sanjeev Manadhar, Texas Instruments Hybrid electric vehicles (HEVs) and electric vehicles (EVs) are popular because they have low (to zero) emissions and fewer maintenance requirements while offering better efficiency and drive performance. New HEV/EV companies are emerging, while existing automakers are investing more in HEV/EV to compete for market share. The heart of the […]
Tiny, ultra-low-power switching regulator with light-load efficiency maximizes power delivery
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 […]
