Description
The SC811 and SC813 are highly versatile single input triple mode (adapter/USB high current, USB low current) linear single-cell Li-ion battery chargers, each in an 8 lead 2x2 MLPD ultra-thin package. The input will survive sustained input voltage up to 30V to protect against hot plug overshoot and faulty charging adapters. The SC811 has 9.6V rising, 8.2V falling OVP thresholds for general purpose charging with low cost adaptors. The SC813 has 6V rising, 5.6V falling OVP thresholds for customers utilizing charging adapters with specifications that are similar to a USB Vbus supply. The SC811 and SC813 differ only in OVP threshold.
Features
◾ Single input charger with three charging modes
◾ Constant voltage — 4.2V, 1% regulation
◾ Fast-charge current regulation — 15% at 70mA,
9% at 700mA
◾ Charging by current regulation, voltage regulation,
and thermal limiting
◾ Input voltage protection — 30V
◾ Current-limited adapter support capability — reduces
power dissipation in charger IC
◾ USB high and low power modes limit charge current
to prevent USB Vbus overload
◾ Instantaneous CC-to-CV transition for faster charging
◾ Programmable battery-dependent currents (adapter
mode fast- and pre-charge, termination)
◾ Programmable source-limited currents (USB-high
mode fast-charge, and USB-low mode fast- and
pre-charge)
◾ Independent programming of termination current
with dual-mode operation
◾ 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 adapter or USB load transients
◾High operating voltage range of SC811 permits use
of unregulated adapters
◾Complies with CCSA YD/T 1591-2006
◾Space saving 2x2x0.6 (mm) MLPD package
◾WEEE and RoHS compliant
Applications
◾ Mobile phones
◾ MP3 players
◾ GPS handheld receivers
