LT7882, IQOO 80W car charging source of fast charging source

High -power mobile phone fast charging has penetrated into people's daily life, and the charging in just ten minutes can meet the light use of a day.IQOO recently launched a 80W vehicle charger that can support large -capacity 80W PD and 33W UFCS protocol charging, which is convenient for consumers to quickly recover the blood on mobile phones and laptops on their way.

When Sanquan Technology disassembled this car charging, it was found that it was equipped with multi -protocol synchronous lifting booster controller RT7882 from Lizhen Technology.

IQOO 80W car charger

IQOO has a 1A1C interface with a 80W dual-port vehicle charging. Among them, the USB-A port supports 55W fast charging, USB-C port supports 80W PD fast charging, 80W output power is supported when the double port is used at the same time, and both interfaces support 33W UFCSFusion fast charging.

The IQOO 80W double -port flash charging vehicle carrier charger is designed with a classic sub -warhead. The streamlined body is more fast, the surface fine lines matte treatment, and the whole machine feels comfortable.The front body is printed with IQOO brand and uses classic yellow color.Both sides are dual -metal elastic contact design, which is compatible with mainstream cigarette ports and more stable insertion.

Lixuan Technology Synchronous Hollowing pressure controller RT7882

Synchronous lifting controller comes from Richtek 锜 锜 同, model RT7882, which is encapsulated by WQFN-48L 6X6. It is a multi-function USB PD controller that integrates USB-C/PD controller and synchronous lifting pressure controller togetherEssenceThe output voltage range is 3.3V-21V and has passed the USB PD3.1/PPS authentication, which is in line with the USB PD3.1 specification. The USB-C cable and the connector specification 2.1.The chip is built into the built-in VBUS fast discharge pathway, driving the charge pump and linear regulator of the low-cost N-MOSFET switch.

This chip integrated M0 MCU for communication control to achieve protection and customer customization functions.Internal hardware protection of the chip, including the peak value of the inductance current, the protection function of VBUS overvoltage protection, input overvoltage and under voltage protection, output voltage protection and other protection functions.

This chip has recently obtained the UFCS function certification certificate, certification number 0302347160719r0l-UFCS00040.
