ETA6884 is a switch-type lithium battery charger that can provide up to 3 A of charging current to the battery, and
The boost discharge output capacity exceeding 2.4A. It provides a charge pump to provide fast OVP overpressure
Input protection, and contains a power lamp drive system that can adjust the corresponding voltage. When charging, it uses ETA
The patented control circuit is used to simulate the current sampling resistor, so as to achieve constant current control, maximize efficiency, reduce charging
Electricity time and cost reduction. It can also obtain energy boost from the battery to 5 V output in the reverse direction.
It only needs 1 inductor to achieve bidirectional power path management for automatic mode detection and switching
Make. ETA6884 is an ideal all-in-one fully integrated solution, designed for battery charging and discharging applications
Use, such as mobile power, smart phones and tablets and other occasions that require battery charging and OTG output.
ETA6884 uses QFN4x4-28 package.

Since it is a two-in-one charging method, then our mobile power supply and wireless charging can be freely matched. Now the power bank is no longer the previous 5V, 1A input, 5V, 1A output. Now it supports more fast charging methods of PD QC3.0, and also supports different fast charging protocols such as Qualcomm and MTK. The other is the wireless charging part. The power here can also be selected according to customer requirements: 5W 7.5W 10W, of course, 15W can also be done. Only the current 15W transmitter is rare.
