illustrate

The LM3880 power sequencer provides the easiest way to control the drop of multiple power supplies (switchers or linear regulators) for power and power down. Amazing start-up sequence, which is possible to avoid latching conditions or large inrush currents that may affect the reliability of the system.

In the SOT23-6 package, the power sequencer contains a precision enable pin and three open-drain output flags. The three output flags after the enabled LM3880 will be released in turn, and after an individual time delay, the connected power supply will be allowed to start. The output flag will power off in reverse order to avoid latching conditions.

EPROM's ability to make each delay and sequence fully adjustable. National Semiconductor contact, if non-standard configuration is required.
