Ultra-small linear charger IC for Li-ion batteries

Torex Semiconductor XC6810 Linear Charger IC for Li-ion Batteries, available now from Mouser, are provided in an ultra-small (1.17mm x 1.57mm x 0.33mm) WLP-12-01 package that is compatible with wireless charging and contact power supplies.

The charging current (1mA to 25mA) supplies a wide 3.8V to 4.4V charging voltage range. The device components are furnished with a shutdown function to suppress battery discharge when stored or not in use and a wake-up function utilising an external push button, to extend the life of batteries and devices. This IC provides a battery voltage monitoring function, which can directly monitor the battery voltage via a microcontroller or a low battery voltage notification function.

This linear charger IC supports wireless power and energy harvester charging, including solar and hearing aids, wireless earphones/headsets, wearable devices, wireless charging equipment, IoT devices, and smartcards.
