Battery charger delivers termination current of 20 mA

September 3, 2019 By Aimee Kalnoskas

BQ25619 battery charger

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

August 20, 2019 By Aimee Kalnoskas

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

July 16, 2019 By Aimee Kalnoskas

TPS62840 switching regulator

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

June 25, 2019 By Aimee Kalnoskas

current-sensing amps

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

March 12, 2019 By Aimee Kalnoskas

LMLM5164 DC/DC buck converter

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

December 18, 2018 By Bill Schweber

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

November 28, 2018 By Aimee Kalnoskas

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 […]
