SC810EVB(2008) 数据手册 ( 数据表 ) - Semtech Corporation

Description

   The SC810 is a linear single-cell Li-ion battery charger in a 6 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.

Features

◾ Single input charger

◾ Constant voltage — 4.2V, 1% regulation

◾ Fast-charge current regulation — 15% at 70mA,

   9% at 700mA

◾ Three mode charging — current regulation, voltage

   regulation, and thermal limiting

◾ Input voltage protection — 30V

◾ Current-limited charging support — reduces power

   dissipation 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

   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
