ETA6198 Datasheet | ETA

DESCRIPTION ETA6198 is a high efficiency, switching Li-Ion battery charger capable of delivering up to 2.5A of charging current to the battery. For charging, it uses a proprietary control scheme that eliminates the current sense resistor for conventional constant current control, maximizing efficiency, reducing charging time and reducing costs. An OVP function protects the IC itself and its downstream system against input voltage surges. With this OVP function, the IC can stand off input voltage as high as 32V, making it an ideal solution for industrial applications. ETA6198 is suitable for charging a 4.35V Li-ion battery. And ETA6198 is in DFN3x3-10 package.
