The SC811ULTRT 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.
Feature
- 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
Packaging
