Chapter 6. Power

Power for the module is supplied on the
Jetson Orin NX Data Sheet
!
CAUTION: Jetson Orin NX is not hot-pluggable. Before installing or removing the module, the
main power supply (to VDD_IN pins) must be disconnected and adequate time allowed for the
various power rails to fully discharge.

pins and is nominally 5.0V to 20V (see the
VDD_IN
for supply tolerance and maximum current).
Usage and Description
Main power – Supplies PMIC and other
regulators
Real-Time-Clock back-up. Optionally used to
provide back-up power for the RTC in the Power
Sequencer. Connects to a Lithium Cell or
similar power source. The cell sources power
for the RTC when system is disconnected from
power.
Force Recovery strap pin. Held low when
SYS_RESET* goes high (i.e. during power-on)
places system in USB recovery mode. 10kΩ pull-
up to 1.8V on the module.
Sleep/Wake. Configured as GPIO for optional
use to indicate the system should enter or exit
sleep mode. 100kΩ pull-up to 1.8V on the
module.
When driven/pulled low by the module, requests
the carrier board to shut down. ~5kΩ pull-up to
VDD_IN on the module.
Signal for module on/off: high level on, low level
off. Connects to module PMIC EN0 through
converter logic. POWER_EN is routed to a
Schmitt trigger buffer on the module. A 100kΩ
pulldown is on the module.
Module Reset. Reset to the module when driven
low by the carrier board. Used as carrier board
