LM3880 Datasheet Power Sequencer

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. LM3880 Power Sequencer September 2006 LM3880 Power Sequencer General.

General Description

The LM3880 Power Sequencer offers the easiest method to control power up and power down of multiple power supplies (switchers or linear regulators).

By staggering the startup sequence, it is possible to avoid latch conditions or large in-rush currents that can affect the reliability of the system.

Available in a SOT23-6 package, the Power Sequencer contains a precision enable pin and three open drain output flags.

Key Features

  • n n n n n n n Easiest method to sequence rails Power up and power down control Input voltage range of 2.7V to 5.5V Small footprint SOT23-6 Low quiescent current of 20 µA Standard timing options available Customization of timing and sequence available through factory programmability.
