این محصول در انبار موجود نیست
ETA9742 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 bidirectionally with a proprietary automatic mode detect and
switch scheme. ETA9742 is an ideal all-in-one solutionfor 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.
