SYS_VIN_HV Input

The Jetson AGX Xavier Developer Kit carrier board allows the main system power to be
supplied either by one of the USB Type C connectors or a DC power Jack. The details for
implementing Type C for power, etc. can be found in the P2822 reference schematics. If a
design only requires a simple DC power jack, the circuit in the following figure can be used.
Note: Designs that intend to follow the NVIDIA carrier board design and include the Type C PD
Controller (CYPD4226 - U513 on NVIDIA carrier board) need to replicate the circuitry on the
latest P2822 carrier board exactly. NVIDIA will provide the binary and the customer should get
the flashing instructions from Cypress.

Note: Designs which implement an eFUSE or current limiting device on the input power rail of
the module should select a part that DOES NOT limit reverse current.

Power-On

This section details the power-on features for Jetson AGX Xavier.
5.4.1

Power-On No MCU

The Jetson AGX Xavier Developer Kit carrier board implements a button power-on supervisor
circuit that utilizes an EFM8SB10F8G-A MCU from Silicon Labs. For designs that do not want
to use this approach, a circuit that does not use the MCU is shown in the following figure.
