TUSB4020BI-Q1: PD USB Charger&Hub配置问题

Part Number: TUSB4020BI-Q1
Other Parts Discussed in Thread: TPS55289, TPS25772-Q1,

我们现在有一个车载PD USB Charger&Hub的项目:2port输出,1port是纯充电端口,1port是充电+通信功能。目前咨询使用的整体方案是:TPS25772-Q1+TPS55289+TUSB4020BI-Q1,整体方案需要PD功率分配。附件为相关原理图及PCB Layout及SPEC说明。目前需要配置产品功能输出(充电及通信),另外按照客户要求需要禁用J2端口的通信功能,只保持充电功能。请帮忙看看具体怎样配置(充电,通信,使用了两颗I2C EEPROM) ?谢谢!Uniwon PD60W 2UCU&2Hub SPEC updata_20231128.xls
