Rohm Developed A Battery Charge IC That Can Support 2 Power Supply Inputs

I am not quite sure how many people are interested in wireless charging, but I believe the demand is increasing as you see wireless charging pad in restaurants, coffee-shops, hotels, etc.
This Global Market Insight mentions that the wireless charging market size was valued at over 3 billion USD in 2016 and potentially grow more than 13% CAGR from 2017-2024.

This means that more portable devices will start supporting both conventional wired and wireless charging.
People probably use USB for the wired charging, but what is wireless?
Well, there are several technologies when we talk about wireless, such as inductive, resonant, RF, and others.
It seems like inductive charging technology like Qi is the one we hear more often. 
 
Now, how can be implement such a circuitry in the gadget?
Isn't the schematic getting more complected?

Here is the potential solution for you!
Rohm semiconductor's  developed "BD99954GW" and "BD99954MWV" that can support 2 power supply inputs and automatically switch the inputs.
Yes, automatically...and it does not require MCU to control the external switching circuits and simplifies the design and PCB area.
You can refer to the example drawings in the product introduction page here.
The difference between GW and MWV is the package. 
GW is the UCSP package and MWV is the UQFN package.

Another advantage of this part is that this part supports USB BC1.2, USB Power Delivery, as well as AC adapter .
The internal back-boost converter can generates the charging voltage from 3.07V to 19.2V which allows to control 1 to 4 cell batteries and also the USB PD system.
 
With all these features, it will make the design easy for the engineers who are working on the wired and wireless charging system.
