Korean tech giant Samsung is preparing to release Galaxy Note10. However, some details about the configuration and features of the device have not been revealed. According to many speculations, the device will probably support 45W fast charging, the highest of all Samsung smartphones today.
However, these rumors were not groundless when at the MWC 2019 conference in Shanghai recently, Samsung first demonstrated the USB PD 45W charging solution. This is undoubtedly the fast charging solution that the world is familiar with.
Samsung previously released two models of USB Type-C power controller chips. The two models are SE8A and MM101, which support 100W charging sources, in accordance with USB-IF's USB PD 3.0 fast charging standard.
However, there is also information that Galaxy Note10 will be equipped with TA800 chip, supporting 25W fast charging technology.
Samsung's 45W fast charging design prototype
From the reference design you can see, the USB PD 45W charger is equipped with the system of US Power Integrations (PI) and Samsung's own chip, which is responsible for connecting the protocol with the USB PD standard. According to media, Samsung's reference chip model is the reference design of SE8A.
Since the Galaxy Note7 explosion incident was costly and greatly damaged in terms of reputation for Samsung, Korean electronics firms are becoming more and more careful with battery and fast charging issues. That's why the company has maintained 15W (9V 1.67A) fast charging capacity on many recent flagship models.
Not long ago, a source appeared on XDA Developer page, saying that Galaxy Note10 will not support fast charging 45W but only 25W. Meanwhile the new Galaxy A90 model is a fast-equipped 45W fast charging device. Since we don't know how to actually damage, we will need to wait for the Galaxy Note10 launch event in August for more details.
