Semtech SC811

Adapter/USB Tri-Mode Single-cell Li-ion Battery Charger

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.

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

Applications


  • Mobile phones
  • MP3 players
  • GPS handheld receivers
