DRVVBUS is low and PWRFAULT is high. That's the problem. We changed the RCW[SHDC] to 1 so that the DRVVBUS can be controlled as GPIO. As GPIO we could enable DRVVBUS, the 5V were switched on and finally USB devices were detected. So where does this over-current condition comes ...
当插入能提供所需功率的电源时,VBUS_FET_EN 将按预期被驱动为低电平。 当插入无法提供所需功率的电源时,故障变为高电平,SAFE_PWR_EN 变为低电平。 当插入我的笔记本电脑时,故障变为高电平,但 VBUS_FET_EN 和 SAFE_PWR_EN 都处于 VBUS(~5V)。根据我对数据表的阅读,在最后...

PWREN1 stays high, VBUS_P_CTRL_DS1 stays low. Is in the firmware a dependency on the US port? Like the DS1 port will only be enabled, when the US port is connected? As we have the US port directly connected via PCB and no power switch on tha...
