description

The reference design is a programmable single-chip IC solution for fast charge management of NiCd, NiMH or Li-Ion batteries in single or multi-chemical applications. It will use the appropriate battery chemistry (nickel or lithium) and perform the operation using the best charging and termination algorithms. This process eliminates poor charging, undercharging or overcharging and ensures fast charging accuracy and safe termination.

Filter in air purifiers are used to reduce the concentration of contaminants (including dust, pollen, pet dander, mold spores, dust mite feces, smoke particles and volatile organic compounds) found in the environment. These contaminants can act as allergens and pose a health risk. So, Air Purifier is useful and even necessary for people.
