In the Type/Dir column, Output is from Jetson AGX Xavier. Input is to Jetson AGX Xavier. Bidir is for Bidirectional signals.
4.
The output voltage is configurable in the PMIC. It can be disabled if a non-rechargeable source is connected, or set to 2.5V, 3.0V, 3.3V or 3.5V.
Jetson AGX Xavier Series Product
Usage/Description
Standby Acknowledge. Indicates module is in
standby (SC7 state). Signal should only be
observed and not affected by the carrier board. A
buffer on the signal is recommended if it will be
connected in the platform.
Standby Request. Requests module enter standby
(SC7 state). 10kΩ pull-up to 1.8V is present on the
module.
System Reset: Connected to NRST_IO of PMIC.
Bidirectional reset driven from PMIC to carrier
board for devices requiring full system reset. Can
also be driven from carrier board to module to
initiate full system reset (including PMIC) (i.e.
From RESET button). 1kΩ pull-up to 1.8V is
present on the module.
Battery Over-current (and Thermal) warning
Supports either GPIO operation or SoC Thermal
Over-current alert #1.
VDD_IN Power Bad. Carrier board indication to
the module that the VDD_IN power is not valid.
Carrier board should de-assert this (drive high)
only when SYS_VIN_HV/MV have reached the
required voltage levels and are stable. This
prevents SoC from powering up until the main
input supply voltages are stable. 10kΩ pull-up to
5V on the module.
Watchdog Timeout
Force Power Off Request
ALERT*/THERM2 from Temp Sensor on module
Present #[1:0]. Tied together on module. Used to
detect when module is connected to the carrier
board. Can be used to keep carrier board from
powering the module until the module is installed
in the carrier board.
