LM3880MF-1AA/NOPB Datasheet PDF - TI

●The LM3880MF-1AA/NOPB is a simple Power Sequencer offers the easiest method to control power-up sequencing and power-down sequencing of multiple Independent voltage rails. By staggering the start-up sequence, it is possible to avoid latch conditions or large in-rush currents that can affect the reliability of the system. The simple sequencer contains a precision enable pin and three open-drain output flags. When the LM3880 is enabled, the three output flags will sequentially release, after individual time delays, thus permitting the connected power supplies to start up. The output flags will follow a reverse sequence during power-down to avoid latch conditions. EPROM capability allows every delay and sequence to be fully adjustable. Contact Texas Instruments if a nonstandard configuration is required.
