TS3A227E: Vdd rise and fall times

Ryuji

Part Number: TS3A227E

Hello,

Could you please let me know the minimum and maximum Vdd rise and fall times?

In the datasheet P.47 Power supply recommendations section , there is the description that " To ensure a POR trip during a power-down and power-on event the power supply should follow the minimum and maximum V DD rise and fall times specified in the electrical specifications section."

However, I couldn't found the minimum and maximum Vdd rise and fall times from the datasheet.

Best Regards,
Ryuji

    Ryuji,

    Thank you for pointing out that we forgot to include the POR spec in the table referenced in the power supply recommendation.  I have put in a request to our design team to verify the spec so we can add it to the datasheet.

    Thank you,

    Adam

    Thank you for your reply. Please let me know the PoR spec when the team verified the spec.

    Ryuji,

    You have caught an error in our TS3A227E datasheet. We did not intend to mention a POR requirement in the datasheet and are going to remove that statement in the power supply recommendations section.

    Our design team says if your ramp rate is > 4.5 V/ms you will not run into POR issues due to power supply ramp rates.

    I'm sorry for the error.

    Thank you,
    Adam
