ETA9741 SOP-8

ETA9741 SOP-8 

■ETA9741 is a switching Li-Ion battery charger capable of delivering 2A of charging current to

the battery and also capable of delivering up to 5V/2.4A in boost operation, with high efficiency

in both charging mode and boost mode. It also includes a fuel gauge system for power indication.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.It can also output a 5V voltage in the reversed direction by boosting from the battery. It only needs a single inductorto provide power bi-direction ally with a proprietary automatic mode detect and switch scheme. ETA9741is an ideal all-in-one solution for battery charging and discharge applications, such as power banks, smart phones, and tablets with only one USB port that can be used for charging battery function.
■ETA9741 is suitable for charging a 4.2V Li-ion battery. And ETA9741 is in ESOP8 package.
