The SC824 is a single input triple mode (adapter/USB High, USB Low) linear single-cell Li-Ion battery charger in a 10 lead 2x2 (mm) MLPD ultra-thin package.

Features


  • Single input 30V protected charger
  • Adapter, USB High, USB Low modes
  • Charging by current regulation, voltage regulation,
    and thermal limiting
  • Programmable currents from 70mA to 1A
  • Fast-charge current regulation — 15% at 70mA,
    9% at 700mA
  • Constant voltage — 4.2V, 1% regulation
  • Input voltage protection 30V
  • Current-limited adapter support capability — reduces power dissipation in charger IC
  • USB modes automatically reduce charge current if
    needed to prevent USB Vbus overload
  • Instantaneous CC-to-CV transition for faster charging
  • Battery temperature NTC thermistor interface
  • Multi-stage charge timer for safety and alternative
    termination, IEEE Std. 1725-2006 compliant
  • Termination on current or timer — first to occur
  • Soft-start reduces adapter or USB load transients
  • High operating voltage range permits use of unregulated adapters
  • Complies with CCSA YD/T 1591-2006
  • High-current USB Dedicated Charger compatible
