External LVR Power-up Sequence
Power Up-Sequence (Internal LVR)
The 82574L controls the power-up sequence internally and automatically with the
following conditions (see
The ramp is delayed internally, with T
ramp.
Internal LVR Power-Up Sequence
• 3.3 V dc must be the source for the internal LVR.
• 1.9 V dc never exceeds 3.3 V dc.
• 1.05 V dc never exceeds 3.3 V dc or 1.9 V dc.
