Eval board simplifies design of fast charging applications
Silanna Semiconductor has unveiled an evaluation board that simplifies the design, testing, and prototyping of 65 W multi-port USB-PD and QC fast charging applications. Designed to deliver a real-life implementation when used with a front-end AC/DC converter, the SZPL3002AA-EVB03 integrates three Silanna SZPL3002A DC/DC converter ICs, which are the world’s first integrated buck converters to […]
Battery configurations (series and parallel) and their protections
A single cell is not sufficient for some devices. To achieve desired voltage, the cells are connected in series to add to the voltage of the cells. To achieve the desired capacity, the cells are connected in parallel to get high capacity by adding ampere-hour (Ah). This combination of cells is called a battery. Sometimes…
Current sense resistor provides overcurrent protection, monitoring, and control
Littelfuse, Inc. announced the launch of its new Current Sensing Resistor (CSR) family. These new CSRs offer a more cost-effective solution for measuring current within circuits, enabling voltage monitoring, control, and power management of functions such as battery charging and motor speed, while also providing overcurrent protection. The Current Sensing Resistors Series is a game […]
Design the right BMS for LiFePO4 batteries
By JD DiGiacomandrea, Green Cubes Technology Learn why Lithium-ion-phosphate batteries need the right battery-management system to maximize their useful life. It’s all about chemistry. Lithium-ion (Li-ion) batteries provide high energy density, low weight, and long run times. Today, they’re in portable designs. Their popularity has spawned a few sub-chemistries that all use the principle of…
How do the six most common Li primary chemistries compare?
Rechargeable lithium-ion batteries get a lot of headlines, but primary Li battery chemistries are the workhorses in a large number of industrial, medical, consumer, and other applications. This article looks at the performance tradeoffs and typical applications for the six most common Li primary chemistries including LiCFX (lithium poly carbon monofluoride) LiMN02 (lithium manganese dioxide),…
How can primary Li batteries contribute to sustainability?
A lot has been written regarding rechargeable lithium (LI) batteries and sustainability. Primary (non-rechargeable) Li batteries can also make major contributions to improving the sustainability of the systems where they are used. This FAQ reviews some of the factors related to the sustainability of primary Li batteries including key performance indicators (KPIs), downcycling versus recycling,…
6G promises to bring sustainability to telecom
Sustainability is at the heart of 6G research, not just in telecom networks and equipment, but throughout the supply chain. If you perform an internet search on “what is 6G?”, you’ll surely see sustainability. The number of companies with goals to be carbon neutral grows daily; they recognize our collective industry actions can not only…
Tiny prismatic supercapacitor enables design of batteryless or more battery-efficiency devices
