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. […]

100 V, 1 A DC/DC buck converter extends battery life
Texas Instruments introduced a wide-input-voltage (VIN) synchronous DC/DC buck converter with the industry’s best combination of light load efficiency, ease of design and overall power solution cost. The 100-V, 1-A LM5164 step-down voltage converter shrinks board space in rugged battery-powered industrial and automotive power supplies. Used in conjunction with TI’s WEBENCH Power Designer, this new […]
Heat sinks, Part 1: Thermal principles
A heat sink is a non-electronic, passive mechanical component that has a vital role in the reliability and performance of ICs, PC boards, modules, chassis, and more. Heat sinks often don’t get much attention, at least not in the early stages of a design. This FAQ will look at the basic thermal principles of these […]
12-bit, 29-kHz RGB LED drivers boast 29-kHz dimming frequency
Texas Instruments introduced a new family of LED drivers with integrated, independent color mixing, brightness control and a power-saving mode. The LP5018, LP5024, LP5030 and LP5036 enable smooth, vivid color and reduce system power consumption. The devices are the industry’s first to offer a 29-kHz dimming frequency, above human-audible range, to help designers of applications […]
GaN 600-V 50-mΩ/70-mΩ power stages support 10 kW applications
Texas Instruments announced a new portfolio of ready-to-use, 600-V gallium nitride (GaN), 50-mΩ and 70-mΩ power stages to support applications up to 10 kW. The LMG341x family enables designers to create smaller, more efficient and higher-performing designs compared to silicon field-effect transistors (FETs) in AC/DC power supplies, robotics, renewable energy, grid infrastructure, telecom and personal […]
