LM3881 Description
The LM3881 Simple Power Sequencer offers the easiest method to control power up and power down of multiple power supplies (switching or linear regulators). By staggering the start-up sequence, it is possible to avoid latch conditions or large inrush currents that can affect the reliability of the system. Available in VSSOP-8 package, the Simple Sequencer contains a precision enable pin and three open-drain output...
