Part Number:TPS54618
Dear expert,
Can I use another voltage rail on EN pin for power sequencing? I want to enable TPS54618 once another 1.8V rail is ready. I use an RC circuit for EN pin like below.
However, I notice that EN pin has an internal pull up current source, which may finally cause 1.9uA reverse current into my 1.8V rail. Will this be a problem? Maybe I can only use open drain output to EN pin?
