Dialog Semiconductor plc introduced a new power management product family of four new 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 […]
PSMA report addresses reliability of power supply digital control software/firmware
The Power Sources Manufacturers Association (PSMA) has published its ground-breaking Power Supply Software/Firmware Reliability Improvement Report. This report, the result of a year-long project undertaken by PSMA’s Reliability Technical Committee, addresses recommended reliability improvements for power supply digital control software and firmware. This new report attempts to present key findings related to the challenges of […]
Buck converters switch at 4 MHz to power mobile processors
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 […]

USB Type-C power delivery ICs handle HostFlexing and PDBalancing
USB Type-C has become increasingly popular, and with the introduction of Power Delivery (PD), it is now possible to charge more types of devices – and charge faster – than ever before. To remove the traditional complexity and high costs associated with implementing USB Type-C, Microchip Technology Inc. announced two new solutions that simplify USB […]
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 […]
Universal input conditioners and isolators accept wide range of inputs
AutomationDirect’s ProSense universal input conditioners/isolators accept a wide range of RTD, thermocouple, resistance, potentiometer, mA or voltage inputs, and offer current, voltage and/or relay outputs with programmable ranges and functions. The ProSense conditioners operate on 21.6 to 253 VAC or 19.2 to 300 VDC supply voltage and provide 3-way isolation between input, output and power. […]
