Hello,
The datasheet of the LMQ66430-Q1 states that
Open-drain power-good flag output. Connect to suitable voltage supply through a current limiting
resistor. High = power OK, low = power bad. This pin goes low when EN = low. This pin can be
open or grounded when not used.
In my simulation in PSpice for TI, my PG is high all the time. Is there a problem with my circuit or is this a problem with the model?
