Chapter 5. Power
This chapter describes the power specifications for the Jetson AGX Xavier Series module.
!
CAUTION: Jetson AGX Xavier is not hot-pluggable. Before installing or removing the module, the
main power supply (to SYS_VIN_HV and SYS_VIN_MV pins) must be disconnected and the power
rails allowed to discharge to <0.6V.
Note: Additional power, system, and thermal signals related to safety can be found in Section
15.5 “Safety MCU JAXi Only.”

VCC_RTC
−
Real-Time-Clock. Optionally used to provide
back-up power for RTC. Connects to Lithium Cell
or super capacitor on carrier board. PMIC is
supply when charging cap/cell. Super cap or coin
cell is source when system is disconnected from
power.

L62 CARRIER_
POWER_ON
− Carrier Power On. Used as part of the power up
sequence. When asserted, it is safe for the carrier
board to power up. 100kΩ pull-up to 3.3V on
module.
Used to enable 1.8V/3.3V
regulators and routed to
power button supervisor
and discharge circuits.
Output na
L10 FORCE_
RECOVERY_N
SOC_GPIO00 Force Recovery strap pin. Held low when
SYS_RESET_N goes inactive (power-on or reset
button press) to enter force recovery mode.
Routed to Force
Recovery button and
automation header.
Input CMOS – 1.8V
L54 MODULE_
POWER_ON
− Module Power On. Signal to module to start
power-on sequence. Driven by power button
supervisor if implemented. Open-drain if power
button supervisor MCU not implemented. If non-
MCU circuit used, signal should have a 100kΩ
pull-up to VDD_5V.
Generated by power
button supervisor or
non-MCU power-on
circuit.
Input
5.0V Open-Drain
(Non-
MCU case).
CMOS – 3.3V
(Power Button
MCU case)
L58
PERIPHERAL_
RESET_N
−
Peripheral Reset. Driven from carrier board to
force reset of SoC and eMMC and QSPI (no
t PMIC).
100kΩ pull-up to 1.8V on the module.
Unused
Input
CMOS – 1.8V
L61 POWER_BTN_N POWER_ON
Power Button. Used to initiate a system power-
on
and to enter/exit SC7. 3.3V to 1.8V level shifter on
the module.
Generated by power
button supervisor.
Input Open Drain, 3.3V
