Analysis of charging architecture of glory magic 3pro

                                                      glory Magic 3Pro  Charging architecture analysis 

This article is reprinted from personal wechat official account , Welcome to your attention ：FAE Old ice
First of all, I'm not a proud employee ^_, I just analyzed the glory based on some data Magic 3Pro Charging architecture of , Just explain the architecture and my understanding of the architecture , Technology that doesn't involve details , If there is a difference in understanding , Welcome to discuss .

One .Magic 3Pro Charging specification

Wired fast charging

Maximum mobile phone support 11V/6A Super quick charge , compatible 10V/4A or 10V/2.25A Super quick charge , compatible 10V/2A or 9V/2A Quick charge .

Wireless charging

Support 50W Wireless super fast charging , Support wireless reverse charging .

The biggest support 50W Wireless super fast charging , You need to buy glory super fast charging vertical wireless charger separately 2（Max 50W） Or glory super fast charging Wireless car charging 2（Max 50W）.

remarks ： The biggest support 66W Wired super fast charging , It should be used with the original super fast charger . The biggest support 50W Wireless super fast charging , You need to buy glory super fast charging vertical wireless charger separately 2（Max 50W） Or glory super fast charging Wireless car charging 2（Max 50W）. The actual charging power will change intelligently with different scenarios , Please refer to the actual use .

Two .Magic 3Pro Charging architecture

Wired charging

1.11V/6A Super charging 66W It's through 2 road 2:1 Of Chargepump( Nanxin SC8551A) Charge , Every way 33W, The actual power distribution is not necessarily 1:1. Every way Chargepump Before chip use 2PCS NMOS, common D Pole connection , The main purpose is MOS Is to do OVP use , the other one MOS It's time to prevent wireless charging 488AUK The output voltage leaks to the wired charging path .

2. 10V/4A or 10V/2.25A I understand that it's also going up 66W Access to .

3. 10V/2A or 9V/2A Fast charging should go up PMU Charge , Through the platform PMU Integrated charging IC Charge , Should be Buck Charge ( Switch charging ).

Wireless charging

Wireless charging has been used 2 Chip , The silk screen printing is CPS4057GC and 488AUK, Specification not found , I don't know the specific function . But I looked at the surrounding devices ,CPS4057GC It should be a wireless charging chip , It is estimated that the alternating current of the coil is rectified to direct current 20V,488AUK hold 20V Depressurization is 10V, Re pass SC8551A Charge the battery .

Wireless recharge

The wireless recoil path first passes through a Boost chip GW62033 Raise the battery voltage 5V, Then through the load switch ET2095 Output to wireless charging chip , Wireless charging chip turns DC into AC , Then charge the external wireless charging device through the coil .

OTG Charge

OTG Also through a Boost chip GW62033 Raise the battery voltage 5V, Then through the load switch ET2095 Output to charging interface , So as to achieve OTG Charging or other external equipment .
