LMZ30606: INH control using MAX16051 (Power Sequencer IC)

Part Number: LMZ30606
Other Parts Discussed in Thread: LMZ30604, LMZ31710, UCD9081, UCD9090A

Dear Sir/Madam,

I want the opinion on using MAX16051 device to control the INH pins of LMZ30606 (Qty. 1) and LMZ30604 (Qty. 4).

Power Tree :

Board Input 12VDC --> LMZ31710 --> 5VDC --->LMZ30606 (Qty. 1) (1V)

         -----> LMZ30604(Qty. 4) (1V, 1.2V, 1.8V & 3.3V)

MAX16051 used as sequencer IC, powered from 5VDC supply.

Note : INH Pin of LMZ31710 is left open.

Can the OUT[1-5] (open drain) pin connected directly to INH pins of above mentioned devices? Since INH pins have internal pull up and on any power fault or power down sequence the OUT[1-5] pin can pull down to ground and I hope this operation shall disable the outputs LMZ30606 and LMZ30604. While on power Up, the OUT pins goes to high impedance state.

Note: I am not connecting any external pull up resistor to OUT pins of MAX16051 device. I am depending on only the internal pull resistor.

Also I have attached MAX16051 datasheet. Kindly go through the attached datasheet and provide your review.
