TPS53315: Wiring AND possibility of PGOOD of different regulators

NIBIN S

Part Number: TPS53315

Hi,

I am using 4 number of TPS53315RGFT regulators for generating different outputs.

I have to enable other regulator on the basis of proper output of the above regulator. So I need to connect PGOOD of all these to other regulators in sequence.

I need to know whether wiring AND is possible in this case or should I use an AND gate with 4 inputs for the sequence to be followed. \

Please let me know the possibility ASAP.

Thanks and Regards,

You can use a gate or wired AND, depending on your timing requirement.

Hi,

Does all regulator support wiring AND?
Is it a good practice to use wiring AND as I do not really require any delay in power sequence.

Thanks and Regards,

Most all that I can think of are open drain output and can be connected together.
