Texas Instruments LM3880MFE-1AD/NOPB

Description
The LM3880 Simple Power Sequencer provides an easy method for controlling power-up and power-down sequencing of multiple independent voltage rails. By staggering the startup sequence, it prevents latch conditions or large in-rush currents that can affect system reliability.
Available in a 6-pin SOT-23-6 package, the Simple Sequencer includes a precision enable pin and three open-drain output flags. When enabled, the three output flags release sequentially after individual time delays, allowing connected power supplies to start up. During power-down, the output flags follow a reverse sequence to avoid latch conditions.
EPROM capability allows customization of every delay and sequence. Contact Texas Instruments for nonstandard configurations.
