TPS7H4001-SP: specification for PVIN shutdown current

Part Number: TPS7H4001-SP
Other Parts Discussed in Thread: TPS7A4501-SP

I have a question on the shutdown supply current of the TPS7H4001 – the datasheet states 2.85mA max shutdown current for VIN.  Is there a specification for PVIN shutdown current or can I assume <<1uA?

The TPS7H4001 devices will be powered off of a battery so the amount of unnecessary battery leakage current needs to be minimized.  One idea I have is to power the PVIN pins directly off the battery, but power the VIN pin from a TPS7A4501-SP LDO.  The shutdown current for the LDO is only 1uA max so I’m hoping to use it as a type of load switch to bring the overall quiescent current draw in shutdown of both the POL and LDO devices to no greater than 1uA.  Please let me know if there are any issues with this implementation (i.e. PVIN/VIN power sequencing, PVIN/VIN voltage mismatch concerns, etc).
