TPS56428: TPS56428 PG can pull high to 3.3V directly?

Part Number: TPS56428

Dear Sir,

The PG pin has been pull high to VREG on the datasheet.

I have one question need to check with you.

If the PG pin pull high to P3V3_AUX directly. Is there any question?

hi,

Yes, PG pin can be pulled high to P3V3_AUX directly via 100k resistor.

Notice under below situation : (P3V3_AUX ramps up earlier than P12V_AUX)
P3V3_AUX=3.3V & P12V_AUX=0V--->PG should be 3.3V
