The SC820ULTRT 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.
Feature
- 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
Applications
- Mobile phones
- MP3 players
- GPS handheld receivers
Packaging
MLPD-8 2x2
Order Codes
