Datasheet Summary
High Efficiency Switch Mode Li-Ion Battery Charger
The ADP3808A is a plete Li-Ion battery charging controller for 3- or 4- cell battery packs. The device bines accurate final battery charge voltage control with constant current control to simplify the implementation of constant-current, constant-voltage (CCCV) chargers.
The final battery charge voltage is programmable between 4.0 V to 4.5 V per cell, allowing the charging of various cell types. The charge current is programmable over a wide range from trickle charging to full charging. The system current sense amplifier includes an ac adapter detection output to signal that the adapter is connected. The bootstrapped...
