SC810
Single Input/Single Mode
Single-cell Li-ion Charger
POWER MANAGEMENT
Features
Input voltage protection — 30V
Single input charger
Constant voltage — 4.2V, 1% regulation
Charging by current and voltage regulation (CC/CV)
Thermal limiting of charge current
Programmable fast-charge current
Current-limited adapter support — reduces power dis-
sipation in charger IC
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 adapter load transients
High operating voltage range permits use of unregu-
lated adapters

Space saving 2×2×0.6 (mm) MLPD package
Pb free, Halogen free, and RoHS/WEEE compliant
Applications
Mobile phones
MP3 players
Description
The SC810 is a linear single-cell Li-ion battery charger in a
6 lead 2×2mm MLPD Ultra-thin package. The input will
survive sustained input voltage up to 30V to protect
against hot plug overshoot and faulty charging adapters.
Charging begins automatically when a valid input source
is applied. Thermal limiting protects the SC810 from
excessive power dissipation. It can be programmed to
turn off when charging is complete or to continue operat-
ing as an LDO regulator while float-charging the battery.
The input will charge with an adapter operating in voltage
regulation or in current-limit to obtain the lowest possible
power dissipation by pulling the input voltage down to
the battery voltage. The maximum fast-charge current
setting is 1A.
Charge current is programmed with a single resistor. Pre-
charge and termination current are fixed at 20% and 10%,
respectively, of the programmed fast-charge current.
Charge current steps up to the programmed value (soft
starts) to reduce load transients on the charging adapter.
