ETA ETA6198
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. With this OVP function, the IC can stand off input voltage as high as 32V, making it an ideal solution for industrial applications.| Part No. | ETA6198 |
