UB2016 Overview
UTC UB2016 is a plete, constant current and constant voltage linear charger for single cell lithium-ion batteries. Its small size and ability to regulate low charge currents make UTC UB2016 especially well-suited for portable applications using low capacity rechargeable lithium-ion coin cells. Furthermore, UTC UB2016 is specifically designed to work within USB power specifications.
