DRV8889-Q1: Lowest voltage to ensure shut down

Tool/software:

Hi Team,

According to the datasheet, the minimum operation voltage of DRV8889-Q1 is 4.5V.

While we want to confirm what is the voltage level to ensure the device is shut down? For example, can I say the DRV8889 can absolutely shut down when VM is lower than 2.7V?

The reason for asking this is we are working on configure the power up/down logic. If we can ensure a voltage level that the device can absolutely shut down, we can just set the power down voltage level simply below this.

Thanks

Best,

Frank
