LMZ31704: INH On/Off inhibit

Part Number: LMZ31704
Other Parts Discussed in Thread: UCD90160,


The datasheet of LMZ37104 suggests using an external open drain/ collector device, if the application requires On/Off function (page 19 of SLVSBV8A). I have a controller (UCD90160), that can generate the required control signal.

My query is whether I can avoid using an external open drain device and instead drive directly from the controller, and have an external pull-down (around 10kohm). If possible can the details of internal pull-up current source on INH pin be shared

Note that, my design has controller being powered up before any input voltage is supplied to LMZ31704.
