SC810 Single Input/Single Mode Single-cell Li-ion Charger POWER MANAGEMENT Features Description Input voltage protection 30V The SC810 is a linear single-cell Li-ion battery charger in a Single input charger 6 lead 22mm MLPD Ultra-thin package. The input will Constant voltage 4.2V, 1% regulation survive sustained input voltage up to 30V to protect Charging by current and voltage regulation (CC/CV) against hot plug overshoot and faulty charging adapters. Thermal limiting of charge current Charging begins automatically when a valid input source Programmable fast-charge current is applied. Thermal limiting protects the SC810 from Current-limited adapter support reduces power dis- excessive power dissipation. It can be programmed to sipation in charger IC turn off when charging is complete or to continue operat- Instantaneous CC-to-CV transition for faster charging ing as an LDO regulator while fl oat-charging the battery. Three termination options fl oat-charge, automatic re-charge, or forced re-charge to keep the battery The input will charge with an adapter operating in voltage topped-off after termination without fl oat-charging regulation or in current-limit to obtain the lowest possible Soft-start reduces adapter load transients power dissipation by pulling the input voltage down to High operating voltage range permits use of unregu- the battery voltage. The maximum fast-charge current lated adapters setting is 1A. Complies with CCSA YD/T 1591-2006 Space saving 220.6 (mm) MLPD package Charge current is programmed with a single resistor. Pre- Pb free, Halogen free, and RoHS/WEEE compliant charge and termination current are fi xed at 20% and 10%, Applications respectively, of the programmed fast-charge current. Charge current steps up to the programmed value (soft Mobile phones starts) to reduce load transients on the charging adapter.
