Reno7 60W super flash charging architecture
2022-07-06 11:57:00 【FAE Laobing】
According to some information on the Internet OPPO Reno 7 Charging architecture of , Just explain the architecture and my understanding of the architecture , Technology that doesn't involve details .
One . Charging specification
Maximum mobile phone support 60W Super quick charge , Flash charging ,PD/QC.
picture
Two . Charging architecture
Reno7 collocation 10V/6.5A The charger , Super quick charge 60W It's through 2 road 2:1 Of Chargepump( Nanxin SC8547) Charge , Every way 30W, The actual power distribution is not necessarily 1:1.Chargepump Before chip use 1PCS NMOS, The main purpose is MOS Is to do OVP use .PD/QC Charging is through the main platform PMIC PM7250B, PM7250 It's also connected to the front OVP MOS Output , There is no separate front end like the previous design OVP chip .
Anti burn MOS tube : Charge VBUS There is one in parallel on the passage MOS tube ,D Pole to VBUS On ,S Pole to ground . Anti burn MOS The tube mainly detects water ingress at the charging port 、 Foreign matter 、 Turn on anti burn when there is a short circuit MOS tube , Charging current starts from discharging MOS The pipe flows through , Is equivalent to VBUS Short circuit to the ground through a small resistance , At this time, the current will exceed the maximum output circuit of the charger , The charger will have overcurrent protection and no voltage output . To protect .
SC8547 It's Nanxin 2:1 6A Of Chargepump Charging chip , And the glory mentioned in the previous article Magic3 Pro With SC8551A(2:1 8A Chargepump) The function is similar to .
