Description
The SC820 is a dual input (adapter/USB) linear single-cell Li-ion battery charger in an 8 lead 2×2mm MLPD ultra-thin package. Both inputs will survive sustained input voltage up to 30V to protect against hot plug overshoot and faulty charging adapters.
Features
◾ Input voltage protection — 30V
◾ Adapter input automatically selected over USB
◾ Constant voltage — 4.2V, 1% regulation
◾ Charging by current and voltage regulation (CC/CV)
◾ Thermal limiting of charge current
◾ Programmable battery-dependent currents
(adapter-sourced fast-charge & pre-charge, termination)
◾ Programmable source-limited currents (USB-sourced
◾ fast-charge & pre-charge)
◾ Current-limited adapter support — reduces power
dissipation in charger IC
◾ USB input limits charge current — prevents Vbus
overload
◾ Instantaneous CC-to-CV transition for faster charging
◾ Three termination options — float-charge, automatic
re-charge, or forced re-charge to keep the battery
topped-off after termination without float-charging
◾ Soft-start — reduces load transients
◾ High operating voltage range — permits use of
unregulated adapters
◾ Complies with CCSA YD/T 1591-2006
◾ Space saving 2×2×0.6 (mm) MLPD package
◾ Pb free, Halogen free, and RoHS/WEEE compliant
Applications
◾ Mobile phones
◾ MP3 players
◾ GPS handheld receivers
