AM6412: AM64x power up sequence parameters

Thomas Yang55737

Part Number: AM6412

Hi Team,

Is there a detailed timing parameter requirement on AM64x power up sequence?

In datasheet power up sequence section, there is only sequence show but no parameter/timing value between the power up steps.

Customer is asking whether there is restrict timing value on the steps

Thanks

Hi Thomas,

Please refer to the below inputs that needs to be considered

We recommend customer to follow the Power Supply Sequencing specified in section 7.10.2.2 .

Customer should ensure the supply rails used follow the Power Supply Slew Rate Requirements in 7.10.2.1

Customer power supply design should follow the requirements mentioned in the notes after the Figure 7-5. Power-Up Sequencing

Hi Sreenivasa,

So， there is no accurate timing value required during power up steps, right？

Hi Thomas,

An additional note.

When customers use PMIC based power solutions, the sequencing in generally taken care by the PMIC.

In case customers implement discrete power solution, the sequencing has to be built into the design.
