ETA6093
ETA6093
1.2A Switching Charger and 1.2A Boost in One Sot23-5 with Single Inductor
DESCRIPTION
ETA6093 is a switching Li-Ion battery charger capable of
delivering up to 1.2A of charging current to the battery and also
capable of delivering up to 5V/1.2A in boost operation, with high
efficiency in both charging mode and boost mode. 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. ETA6093 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.
ETA6093 is suitable for charging a 4.2V Li-ion battery. And
ETA6093 is in SOT23-5 package.
