AM2632: tPorz timing requirements.

Part Number: AM2632
Other Parts Discussed in Thread: TPS65313-Q1,

Tool/software:

I'm having a hard time understanding the power up sequence timing for the AM2632 chip, particularly around the value shown in the below diagrams tPorz. I'm attempting to use a combination of power management TPS65313-Q1, and power management chip TLV840MADL12DBVRQ1 in order to control the timing sequence for the power up. I cannot find any value of what tPorz should be, and if there are any constraints on tPGood + tPorz that I need to make sure are met. 

  • Hello Eric,

    It is effectively 0ms. Once the power good signals are all clear, then PORz can be applied.

    The only thing to keep in mind with tPGood + tPorz is that you need to ensure tSU_SOP for the SOP pins is being followed. Typically not a concern but wanted to make that clear.

    Best Regards,
