I’m design an auto-power-on circuit for the AGX Orin Industrial module. It will auto-power-on when power is applied and after a software or event shutdown must be power cycled to be powered on again.
From the design guide:
VDDIN_PWR_BAD_N, MODULE_SHDN_N and TEMP_THERM signals are essentially all tied together. If any of these signals go down, then all signals go down together, initiating an event based shutdown.
If these are all tied together on the module, can I just then ignore MODULE_SHDN_N and TEMP_THERM and leave them floating, and simply make only a falling edge of VDDIN_PWR_BAD_N to cause MODULE_POWER_ON to latch low during power-off?
