SC820数据手册集成电路（IC）的电池充电器规格书PDF

描述 Description

The SC820 is a dual input (adapter/USB) linear single-cell Li-ion battery charger in an 8 lead 2x2 MLPD ultra-thin package. Both inputs will survive sustained input voltage up to 30V to protect against hot plug overshoot and faulty charging adapters.

特性 Features

·Dual input charger automatically selects adapter input over USB
·Constant voltage — 4.2V, 1% regulation
·Fast-charge current regulation — 15% at 70mA, 9% at 700mA
·Three mode charging (current regulation, voltage regulation, thermal limiting)
·Input voltage protection — 30V
·Current-limited adapter charging support — reduces power dissipation in charger
·USB input limits charge current to prevent Vbus overload
·Instantaneous CC-to-CV transition for faster charging
·Programmable battery-dependent currents (adaptersourced fast-charge & pre-charge, termination)
·Programmable source-limited currents (USB-sourced fast-charge & pre-charge)
·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 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
