Carrier_pwr_on time from auto power on in Jetson TX2

Hi,

Jetson TX2 OEM datasheet describes how it is implemented an auto power on circuit, which is enabled if CHARGER_PRSNT# is tied to GND. This auto power on circuit allows a delay >300ms since VDD_IN >5.5V for a correct power on of the Tegra. However, OEM does not specify next steps in the auto power on.

When is the CARRIER_PWR_ON signal activated in auto power on? Is there some specific delay to activate CARRIER_PWR_ON?

Thank you very much,
Antonio.

Hi Antonio, you can refer to figure 3, Power Up Sequence, t5-6, Jetson TX2 System Power On to CARRIER_PWR_ON, it is same duration for auto power on or power button.
