LITHIUM-ION BATTERY CHARGER IC BASED MAXIMUM POWER POINT TRACKING SYSTEM
In an era characterized by the internet of things (IoT), more connectivity means more outdoor devices are now battery-powered and constantly communicating. In particular, an increasing number of outdoor devices are being powered through solar panels. The charger should be suitable for maximum power point tracking (MPPT) in outdoor designs with a solar panel. This article illustrates design tips fo...
HOW TO ACHIEVE FAST CHARGING WITH USB PD IN PORTABLE DEVICES
Today’s consumers want to conveniently and quickly charge their portable devices anywhere, whether they are in a business center or shopping mall, or waiting for a flight or train. However, there are many different types of charging adapters and connectors, which can make determining which charger or chargers to have on hand confusing for the end user. If the consumer has to carry multiple d...
HOW TO SELECT A LITHIUM-ION BATTERY CHARGE MANAGEMENT IC
John B. Goodenough, considered the father of lithium-ion (Li-ion) batteries, became the oldest Nobel Prize winner when he was awarded the Nobel Prize in Chemistry in 2019 for his pioneering work. Nowadays, Li-ion batteries are utilized in all aspects of life for most consumers since they make electronic devices lightweight and long-lasting. For example, most mobile phones rely on a Li-ion battery ...
BATTERY CHARGER WITH MPPT REFERENCE DESIGN
HIGHLY INTEGRATED BATTERY-CHARGING SOLUTION WITH INNOVATIVE POWER PATH MANAGEMENT
To achieve compact design for battery-powered devices, the battery is usually not removable and the capacity is limited by the space reserved for the battery. As a result, the operation time of the device is a major concern as devices are built with more and more power-consuming functions. To improve the portability of battery-powered devices, another auxiliary charging device with greater battery...
