SGM864S Overview
The SGM864S is an integrated, 4-rail power sequencer. It controls the power-up and power-down sequence of four power supplies by pulling their enable or shutdown pins high or low. Staggered start sequence can avoid the impact of latch conditions or large inrush current on system reliability.
