OEMs are moving away from NiCd and lead-acid batteries to embrace the more environmentally friendly Li-ion battery chemistries. Li-ion batteries are smaller, weigh less, and deliver longer battery life, but require monitoring and protection for safe use. Intersil’s ISL94203 3-to-8 cell battery pack monitor functions as a stand-alone battery management system for rechargeable Li-ion battery packs. […]
Battery Management
Battery Types and Operation
I came across an interesting new product recently which made me realize that I take batteries for granted without actually thinking much about how they work. I know they work and the specifications enable me to select them and design them into a product but how do they work? The product that caused my intrigue […]
Double Data Rate (DDR) termination regulators with built-in power MOSFETs
ON Semiconductor has introduced a series of new high performance devices to support double data rate (DDR) memory, the NCP51200, NCP51400, NCP51510, and NCP51199 feature. All the regulators feature a built in Power MOSFETS and are targeted at a wide variety of applications in the computing, data networking, industrial and handheld consumer markets for specific applications […]
Coin Cell dimensional tolerance and battery holders
Competing brands of batteries can have substantially different dimensional specs. Where this dimensional tolerance has an impact is in the battery holder. A coin cell holder must be designed so it can handle normal height variances while at the same time, not accept batteries of a different type. Obviously, the battery holder can’t have a […]
Better barriers make lithium batteries hard to beat
An advanced barrier between the electrodes in lithium-ion batteries could help head off fires and overheating that occasionally arises in laptops or industrial applications. The barrier uses nanofibers extracted from Kevlar. The barrier helps minimize the growth of metal tendrils on battery electrodes that can otherwise lead to electrical shorts. In normal battery operation, there […]
Small batteries pack big wallop for wireless devices
by Sol Jacobs, Tadiran Batteries Battery makers have devised chemistries that put a lot of energy in a tiny volume. Generally speaking, every penny counts when it comes to designing devices for a mass consumer market. That’s one reason smartphones use relatively inexpensive, rechargeable lithium polymer batteries for power. Constructed from a thin, flexible material, […]
