ON Semiconductor offers a portfolio of a Battery Fuel Gauge devices for 1-Cell Lithium-Ion/Lithium-Polymer batteries integrating smart charge and monitoring capabilities into the industries smallest PCB footprint. They feature a unique algorithm called HG-CVR2 to accurately measure a battery’s RSOC (Relative State of Charge) even under unstable conditions such as changes in battery temperature, loading, aging, and self-discharge. They also offer reporting and alarm functions to support battery safety. Applications include a variety of mobile devices from cell phones, portable headsets, tablets, wearables, and portable game players.
