SC813中文资料适配器/USB三模式单节锂离子电池充电器数据手册Semtech规格书

描述 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.

特性 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 — fl oat-charge, automatic re-charge, or forced re-charge to keep the battery topped-off after termination without fl oat-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

应用 Application

·Mobile phones
·MP3 players
·GPS handheld receivers
