LM3880: Suggestion of EN Circuit

SVJS

Part Number: LM3880

I am planning to use the below attached circuit for Power Sequencing. Can you please suggest an Enable Circuit for this?

For the EN circuity, it is really up to what you want to achieve.

If you only care the power on sequencing, you can add follow below

if you care both power on and off, the EN shall be driven external.

BTW the drawing was from Me. where did you get it?

Hi,
I need to take care of Power ON and OFF sequence.
Can you please suggest an External circuit for this?

I got it from TI Forum only.

Thank you for support.!

The EN is a logic signal, it can be from your host's GPO, can be a output signal from a voltage comparator/supervisor.
