DRV8316: Regarding internal buck regulator

Hi support team.

My customer has asked me regarding internal buck regulator.

there are three questions.

1.  What happens when the buck regulator is disabled (BUCK_DIS bit = 1) after the DRV8316 is started?

   SW_BK is Hi-z, is this correct?

2. When buck regulator is disabled, are BUCK_UV and BUCK_OCP disabled?

3. When the initial value of the BUCK_PS_DIS bit is 0, is the switch setting connected to VM or VBK?

Best Regards,

HIga
