TPS25990: Reverse Current Specification

Part Number: TPS25990

Tool/software:

I do not think the question in the following forum thread was completely answered:

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1223229/tps25990-reverse-current-protection?tisearch=e2e-sitesearch&keymatch=tps25990#

with regard to the request for the specifications for reverse current.

The datasheet specifies VOUTMAX as MIN(20, VIN + 0.3).  Obviously, the body diode of the FET starts to conduct if VOUT exceeds VIN.  What I would like to understand is how much current (reverse current) can the body diode sustain?  In my use case there is a chance the end user could apply a voltage exceeding VIN to VOUT.  It is necessary for me to understand how the device behaves in this situation.  Specifically, the following situations could occur in my use case:

VIN = 5V and user applies VOUT = 12V

VIN = 0V (VIN supply is powered off) and user applies VOUT = 5V

VIN = 0V (VIN supply is powered off) and user applies VOUT = 12V
