    \$\begingroup\$ I'm just wondering, if you don't know what it is why do you want to use one? \$\endgroup\$ – Transistor Mar 21 '20 at 10:34
  • \$\begingroup\$ Using reset and power supply sequencers is a subject in its own right. TI provides reference designs for this series which you should study before trying to do your own design (especially if you have never designed with sequencers before). See ti.com/reference-designs/… \$\endgroup\$ – Peter Smith Mar 21 '20 at 11:01

A programmable power-up sequencer is a chip that turns all supply voltages on (and off) in a specific order and with specific time delays that are necessary for the system to avoid malfunction and damage from getting powered in wrong order. How to use it will depend on the specific requirements for the powered system.
