SW3518S full protocol fast charging power module

Overview

Battery power management chip SW3518S

The module can be directly plugged into DC5.5. It can charge all kinds of mobile phones, has high power and a relatively comprehensive agreement.

Input voltage 12-28V. Do not overpressure.

Multi-fast charging protocol dual-port charging solution supporting PD

SW3518 is a highly integrated multi-fast charging protocol dual-port charging chip that supports fast charging output from any A+C port and supports independent current limiting for dual ports. It integrates a 5A high-efficiency synchronous buck converter, supports multiple fast charging protocols such as PPS/PD/QC/AFC/FCP/SCP/PE/SFCP/VOOC, CC/CV mode, and dual-port management logic. Only a small number of peripheral components are needed to form a complete high-performance multi-fast charging protocol dual-port charging solution.

Has anyone encountered this problem? The pins are hidden.
Hello everyone, I wonder if you have encountered this problem before. Why can't pin 0 be hidden? I tried to click pin 0 alone and hide it in the properties, but it didn't work. Then I drew a new packa
AM335x learning experience: kernel optimization method
