Hi all
Would you mind if we ask TPS65251?
The datasheet shows followings;
-The PGOOD pin is pulled low when any buck converter is pulled below 85% of the nominal output voltage.
-The PGOOD is pulled up when all three buck converters’ outputs are more than 90% of its nominal output voltage and reset time of 1 second elapses.
When Vin is UVLO(under 4.1V) and all three buck converters’ outputs(Vout1 to 3) are more than 90%(PowerGood is pulled up),
will Power Good pin be pulled low or pulled high? We could find it on the datasheet.
(We guess that it will be pulled low.)
Kind regards,
Hirotaka Matsumoto
