ADP3808A
High Efficiency Switch Mode Li-Ion Battery Charger
The ADP3808A is a complete Li-Ion battery charging controller for 3− or 4−cell battery packs.
The device combines 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.
