8.3.3.9 Power-Up and Power-Down Behavior

Device is in OFF or POR state when the device is not powered. STx and VOUTx are in the high-Z state.

After the VS>VS_UVPR and VDD > VDD,UVLOR, the device is ready for full operation.

In case the VDD power supply is enabled first and the VDD voltage exceed VDD,UVLOR before the VS supply is up and VS voltage exceeds VS_UVPR, the outputs remain disabled.
