FEATURES  
DESCRIPTION  
The LM3880 Power Sequencer offers the easiest  
2
Easiest Method to Sequence Rails  
Power Up and Power Down Control  
Input Voltage Range of 2.7V to 5.5V  
Small Footprint SOT-23-6  
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.  
Low Quiescent Current of 25 µA  
Standard Timing Options Available  
Available in  
a SOT-23-6 package, the Power  
Sequencer contains a precision enable pin and three  
open drain output flags. Upon enabling the LM3880  
the three output flags will sequentially release, after  
individual time delays, permitting the connected  
power supplies to startup. The output flags will follow  
a reverse sequence during power down to avoid latch  
conditions.  
Customization of Timing and Sequence  
Available through Factory Programmability  
LM3880Q is AEC-Q100 Grade 1 Qualified and  
is Manufactured on an Automotive Grade Flow  
APPLICATIONS  
EPROM capability allows every delay and sequence  
to be fully adjustable. Contact Texas Instruments if a  
non-standard configuration is required.
