A new power management product family consists of four sub-PMICs that offer best-in-class transient response and in-circuit digital programmability, in a smaller form factor than current market solutions. The new product family of buck converters, which consists of the DA9217, DA9220, DA9121 and the DA9122, represents Dialog’s first sub-PMIC family with a 4-MHz switching frequency […]
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 […]
Want a new perspective on battery management? Buy a plug-in EV.
One facet of EV ownership: Thinking of your daily commute power consumption as equivalent to the sunlight hitting 20 ft2 of your lawn. Rudye McGlothlin, Silicon Labs Earlier this year I took my first step into the EV future by buying a plug-in hybrid electric vehicle (PHEV) – a Chevrolet Volt. A unique car in […]
Li-ion battery management IC for hybrid and electric vehicles
Renesas Electronics Corporation announced its fourth-generation lithium-ion (Li-ion) battery management IC that offers unmatched lifetime accuracy. The ISL78714 provides accurate cell voltage and temperature monitoring, along with cell balancing and extensive system diagnostics to protect 14-cell Li-ion battery packs while maximizing driving time and range for hybrid and electric vehicles. The feature-rich ISL78714 monitors and […]
Power Integrations charges ahead with GaN-on-Sapphire-based switches
Just one day after Yole Dévelopment released a report detailing a Power Integrations’ GaN-on-Sapphire HEMT IC found in the Anker‘s PowerPort Atom PD 1 wall charger (released at CES in January), the supplier of high-voltage integrated circuits for energy-efficient power conversion announced today the new family of offline CV/CC flyback, GaN-based InnoSwitch3 AC-DC converter ICs. 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 […]
Low dropout voltage regulator IP core optimized for battery-powered devices
Vidatronic, Inc. announced the release of the latest addition to their Power Quencher series, the VLDS0300LS130, a low dropout (LDO) voltage regulator IP core optimized for battery-powered devices where low power is critical. The VLDS0300LS130 Power Quencher IP core is a low-power, fully-integrated LDO voltage regulator that achieves a low-noise output voltage without the use […]
TMR-based closed-loop sensors target high-current, coreless apps
TDK Corporation is expanding its Micronas magnetic sensor portfolio with the CUR 423x sensors developed for current measurements in automotive and industrial applications. The new sensors, marketed under the trademark curSENS, are the first Micronas branded products based on the TDK TMR technology. This technology has already been proven in existing TDK automotive sensor products […]
