DATA SHEET AAT3783 1-A Linear Li-Ion/Polymer Battery Charger with 28V Over-Voltage Protection General Description The AAT3783 BatteryManager™ is a single-cell LithiumIon (Li-Ion)/Li-Polymer battery charger IC, designed to operate from USB ports, AC adapter inputs, or from a charger adapter up to an input voltage of 6.
5V.
For increased safety, the AAT3783 also includes over-voltage input protection (OVP) up to 28V.
The AAT3783 precisely regulates battery charge voltage and current for 4.
2V Li-Ion/Polymer battery cells through an extremely low RDS(ON) switch.
When charged from an adapter or a USB port, the battery charging current can be set by an external resistor up to 1A.
In the case of an...
