ETA9740
DESCRIPTION FEATURES
ETA9740 is a switching Li-Ion battery charger capable of
delivering up to 3A 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 inductor to provide power
bi-directionally with a proprietary automatic mode detect and
switch scheme. ETA9740 is 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.
ETA9740 is suitable for charging a 4.2V Li-ion battery. And
ETA9740 is in ESOP8 package.
