Hi,May I ask if the BQ25703a module has a stop or turn off mode? I have noticed that when VBUS is powered on, there is a voltage output at the VSYS pin. Can the VSYS output be turned off after power is supplied。

Hi, Lan,
Yes, you can enter HIZ mode. The converter will stop switching, thus no VSYS is generated.
There are two ways to enter HIZ mode, either set EN_HIZ=1 or pull down ILIM_HIZ to GND.
