    描述 The LM3880 Simple Power Supply Sequencer offers the easiest method to control power up sequencing and power down sequencing of multiple Independent voltage rails. 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 6-pin SOT-23-6 package, 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.特性Qualified for Automotive Applications AEC-Q100 Qualified With he Following Results:Device Temperature Grade: ?40°C to 125°C Operating Junction Temperature Range Easiest Method to Sequence Rails Power-Up and Power-Down Control Tiny Footprint Low Quiescent Current of 25 μA Input Voltage Range of 2.7 V to 5.5 V Standard Timing Options Available Customization of Timing and Sequence Available Through Factory Programmability
