请问下 OTG PIN脚 一直拉高, Boost Mode模式下,VBUS上是否会出现5V?
另外在这种模式下 Boost Mode模式下,插上5V适配器(普通适配器,只有5V 和GND),是否会切换成普通充电模式? 如不会是否IC会有指示 有适配器插入? 可以根据此来判断设置OTG脚来切换模式了?
谢谢了!
Star Xu:
If OTG is enabled and only the battery is connected, then VBAT must be above 3 V to support OTG mode, as shown in the EC table below. In OTG mode, the BQ25606 will maintain 5.15 V at VBUS, and VSYS will be equal to VBAT minus the voltage drop across the BATFET. Please see Section 8.3.3 in the datasheet for more details about OTG mode operation.

when the device is running in OTG mode, plugging is an adaptor will not be detected and the device keeps operating in Boost mode.
