Hi Team,
we have a question regarding the power sequence in three supply mode.
VDDIO = 1.8V ( TPS62826ADMQ same for VDDA1P8)
VDD1P0 = 1.0V ( TPS62826ADMQ)
VDDA2P5 = 2.5V ( LDO)
VDDA1P8 = 1.8V (TPS62826ADMQ same for VDDIO)
2.5V LDO is used for single DP83867IS
Do you see any problem with following sequence? : 5V -> 1V ( VDD1P0 ) -> 1.8V ( VDDIO and VDDA1P8 ramped up at the same time) -> 2.5V ( VDDA2P5 )
Br,
d.
