ETA9742
3A Switching Charger, 2.4A Boost and 3 LED-indicators for battery level, charge/discharge status in One ESOP8 with Single Inductor
DESCRIPTION
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 solution for battery charging and di...
