+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.

## How USB Type-C 12V Fast Charging Trigger Works
26 40
27 41
A USB Type-C 12V fast charging trigger is a small device or circuit that negotiates with a USB Type-C power source (such as a charger or power bank) to output 12V instead of the default 5V. This is done using the USB Power Delivery (PD) protocol.
