Forum Post: AM3352 resetin_out

Hi,

We are planning to give the manual reset input and NRESPWROn from TPS65910 as PORz for AM3352. And then RESETIN_OUT will be used as reset for other components present on board.  I have one doubt -

Does this RESETIN_OUT pin remains low from start (when the AM3352 is powered up)?

If it goes high in start even for a small duration this will not act as power on reset for other components on board. Also as it becomes a open drain output with a weak internal pull up after the PORZ is high, I can't provide any external pull down on this pin. 

Thanks & Regards,

Nikhil
