This USB/AC Li-Ion battery charger is targeted for portable applications. The charging current can be adjusted from 60mA up to 1.1A through an external resistor or by digital control. The current provided to the system can also be adjusted up to 1.8A through the same procedure. This IP features a dynamic power management (DPM) which automatically reduces the charging current when the limit current may cause the system to fall.
This IP also had a features bulk voltage control which connects the substrate of the power device correctly in order to prevent damage on the circuit.
