TPS22953-Q1: Reverse current block active when no V_in and V_bias?

Part Number: TPS22953-Q1

Tool/software:

Dear TI-team,

I have a question about the reverse current blocking feature. In the datasheet I read, that RCB is active when EN=0 or there is a failure event (SNS, thermal shutdown).

What happens when no V_in and no V_bias is present? Is the RCB activated aswell? I want to prevent V_in and V_bias being backpowered from V_out.

Best regards,

Benedikt
