Part Number: TAS6424L-Q1

Hi,

According to Section 9.3.8.7, the POR warning bit and nWARN pin will be asserted on startup.

Do we have a timing specification for this? (Ie: X ms after VDD goes high)

Thanks,
Tyler

Tyler,

At turn on, this is a race condition on how fast the 3.3Vdc power supply rises. Therefore, we cannot specify a time. If you are seeing the warning and the POR fault, the 3.3Vdc is good.

Hey Gregg,

Understood...I have a fairly specific concern here, so I'll follow up via email.
