Battery Management products are TPMICs (Total Power Management ICs) that manage the charging, sequencing and protection of lithium-ion/polymer batteries in personal portable electronics. Skyworks' linear and switching chargers are designed for single and/or dual cell lithium-ion/polymer batteries. These full-featured battery management ICs maximize charging speed and minimize power loss during power delivery to the system. Additionally, they offer integrated system protection using USB and/or adaptor input and dynamic charging capabilities. Many of these products contain unique circuit features to provide advanced IC thermal management during charging and proprietary input power control when supplied from USB port sources. New additions to this product line also feature over voltage protection up to 28V.
