Battery charger

Today's intensive use of smartphones, tablets, and other handhelds means that these devices must be recharged often, sometimes several times in a single day. To ensure consumers' electronic devices remained charged on the go, there is an increasing demand for efficient battery chargers or power banks. With the wide diversity of the types of devices on the market including LED flashlights, cameras, and even laptops, there are many technologies and associated standards to ensure interoperability and the best possible charging speeds. To help fight users' low-battery anxiety, various types of charging devices are available. From fast chargers, including the proprietary Quick Charge (QC) battery charging protocol, and inductive charging (also known as wireless charging) systems to the latest USB-C Power Delivery technology, many solutions exist to ensure users' peace of mind whenever wall outlets are out of reach.

Key Challenges

In order to meet user demands, battery chargers for smartphones, notebooks, and tablets need to be small, thin, and lightweight. In addition to being highly efficient, portable chargers and power banks must ensure ultra-low current consumption in standby for the longest possible charge holding time.

In terms of certification, battery charger designs must include the appropriate EMI and overvoltage protection to prevent or immediately stop dangerous operating conditions. This why it is important to ensure safe charging and discharging by using high-quality power management and monitoring ICs with accurate voltage, current and temperature sensing and control features.
