The first part of EEWorld’s two-part “virtual roundtable” discussion on energy harvesting considers technical challenges and design tradeoffs for engineers using energy harvesting power sources. Joining us for this virtual roundtable are: Dr. André Mansano (AM), CTO at Nowi; Graeme Clark (GC), Marketing Manager, Energy Harvesting Business Unit, at Renesas Electronics, Ken Imai (KI) Sr. […]
Buck-boost charger ICs for USB Type-C and USB Power Delivery ports hit 97% charging efficiency
Texas Instruments introduced the industry’s smallest buck-boost battery charger integrated circuits, which integrate power-path management for maximum power density and universal and fast charging at up to 97% efficiency. The BQ25790 and BQ25792 support efficient charging and 10 times lower quiescent current through USB Type-C and USB Power Delivery (PD) ports in small personal electronics, […]
Battery-management IC extends driving range, reliability, and safety of EVs
STMicroelectronics has revealed new battery-management technology that increases reliability, safety, driving range, and cost-effectiveness of electric vehicles (EVs). EVs are predicted to reach cost parity with conventional combustion-engine vehicles before the end of this decade and overtake in sales volume by 2038. ST, leveraging its technical capabilities to help carmakers achieve these goals, has announced an […]
Thermal propagation triggering and mitigation in medium- and large-format battery modules
by Iris Su, Project Engineer II, Inventus Power A recent change in Li-ion battery pack safety is the shift from a focus on just prevention to one that emphasizes prevention and mitigation. Battery pack designers who were once focused on preventing thermal runaway (TR) are now taking increasing measures on preventing single cell failures within […]
Super-efficient dc-dc converters target fast-charging mobile device apps
Halo Microelectronics announced two new products that utilize switched capacitor architecture to deliver 98% efficiency DC-DC conversion, which outperforms traditional DC-DC converters by up to 10% efficiency. This higher efficiency significantly reduces the thermal dissipation in mobile devices such as smartphones, thus enabling more power to be delivered to the battery and resulting in a […]
USB BC 1.2-compliant battery charging detector incorporates host and client circuitry
Diodes Incorporated today announced the dual-role PI3USB9201 USB BC 1.2 detector, which incorporates both host and client circuitry, enabling designers to optimize the BoM size and cost of adding USB Type-C interface circuitry in devices such as laptops, tablets, smartphones, drones, and small home appliances. Unlike current market solutions that require devices dedicated to either […]
ASIL-D-compliant battery management IC supports multiple cell module configurations
Designers can now achieve ASIL-D compliance for automotive applications using just a single chip for a safer, more cost-effective battery management system with the MAX17853 battery monitor IC from Maxim Integrated Products, Inc. Targeting mid-to-large cell count configurations for automotive applications, such as battery packs for electric and hybrid vehicles, MAX17853’s unique flexible architecture called […]

Energy efficient supercapacitor cell balancers include over-voltage protection
The precision dual-channel SABMBOVP2XX family of products automatically balances supercapacitors with the addition of over-voltage protection (OVP). The result is energy-efficient supercapacitor balancing, ideal for products that require low-loss energy power, leakage current regulation, and OVP. Supercapacitor cells typically operate at a nominal recommended working voltage. However, voltages that exceed the maximum rating for a […]
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 […]
