Figure ? is the high level block diagram of the power section of the board.
(Block Diagram for Power)
The Texas Instruments TPS6590379ZWSR device is an integrated power-management IC (PMIC) specifically designed to work well ARM Cortex A15 Processors, such as the AM5729 used on BeagleBone® AI. The datasheet is located here https://www.ti.com/lit/ds/symlink/tps659037.pdf
The device provides seven configurable step-down converters with up to 6 A of output current for memory, processor core, input-output (I/O), or preregulation of LDOs. One of these configurable step-down converters can be combined with another 3-A regulator to allow up to 9 A of output current. All of the step-down converters can synchronize to an external clock source between 1.7 MHz and 2.7 MHz, or an internal fallback clock at 2.2 MHz.
The TPS659037 device contains seven LDO regulators for external use. These LDO regulators can be supplied from either a system supply or a preregulated supply. The power-up and power-down controller is configurable and supports any power-up and power-down sequences (OTP based). The TPS659037 device includes a 32-kHz RC oscillator to sequence all resources during power up and power down. In cases where a fast start up is needed, a 16-MHz crystal oscillator is also included to quickly generate a stable 32-kHz for the system. All LDOs and SMPS converters can be controlled by the SPI or I2C interface, or by power request signals. In addition, voltage scaling registers allow transitioning the SMPS to different voltages by SPI, I2C, or roof and floor control.
One dedicated pin in each package can be configured as part of the power-up sequence to control external resources. General-purpose input-output (GPIO) functionality is available and two GPIOs can be configured as part of the power-up sequence to control external resources. Power request signals enable power mode control for power optimization. The device includes a general-purpose sigma-delta analog-to-digital converter (GPADC) with three external input channels.
Figure 23 below shows how the USB-C power input is connected to the TPS6590377.

There are 5 User Programmable LEDs on BeagleBone® AI. These are
connected to GPIO pins on the processor.
The table shows the signals used to control the LEDs from the processor. Each LED is user programmable. However, there is a Default Functions assigned in the device tree for BeagleBone® AI:
| LED | GPIO SIGNAL | DEFAULT FUNCTION |
|---|---|---|

The expansion interface on the board is comprised of two 46 pin connectors, the P8 and P9 Headers. All signals on the expansion headers are 3.3V unless otherwise indicated.
NOTE: Do not connect 5V logic level signals to these pins or the board will be damaged.
NOTE: DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.
Figure ? shows the location of the expansion connectors.
The location and spacing of the expansion headers are the same as on BeagleBone Black.
Table ? shows the pinout of the P8 expansion header. Other signals can be connected to this connector based on setting the pin mux on the processor, but this is the default settings on power up. The SW is responsible for setting the default function of each pin. There are some signals that have not been listed here. Refer to the processor documentation for more information on these pins and detailed descriptions of all of the pins listed. In some cases there may not be enough signals to complete a group of signals that may be required to implement a total interface.
The PROC column is the pin number on the processor.
The PIN column is the pin number on the expansion header.
The MODE columns are the mode setting for each pin. Setting each mode to align with the mode column will give that function on that pin.
NOTE: DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.

Notes regarding the resistors on muxed pins.
Table ? lists the signals on connector P9. Other signals can be connected to this connector based on setting the pin mux on the processor, but this is the default settings on power up.
There are some signals that have not been listed here. Refer to the processor documentation for more information on these pins and detailed descriptions of all of the pins listed. In some cases there may not be enough signals to complete a group of signals that may be required to implement a total interface.
The PROC column is the pin number on the processor.
The PIN column is the pin number on the expansion header.
The MODE columns are the mode setting for each pin. Setting each mode to align with the mode column will give that function on that pin.
NOTES:
In the table are the following notations:
PWR_BUT is a 5V level as pulled up internally by the TPS6590377. It is activated by pulling the signal to GND.
(Actually, on BeagleBone AI, I believe PWR_BUT is pulled to 3.3V, but activation is still done by pulling the signal to GND. Also, a quick grounding of PWR_BUT will trigger a system event where shutdown can occur, but there is no hardware power-off function like on BeagleBone Black via this signal. It does, however, act as a hardware power-on.)
NOTE: DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.
(On BeagleBone Black, SYS_RESET was a bi-directional signal, but it is only an output from BeagleBone AI to capes on BeagleBone AI.)

The design materials referred to in this document are *NOT SUPPORTED* and DO NOT constitute a reference design. Support of the open source developer community is provided through the the resources defined at https://beagleboard.org/support.
THERE IS NO WARRANTY FOR THE DESIGN MATERIALS, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE DESIGN MATERIALS “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE DESIGN MATERIALS IS WITH YOU. SHOULD THE DESIGN MATERIALS PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
This board was designed as an evaluation and development tool. It was not designed with any other application in mind. As such, the design materials that are provided which include schematic, BOM, and PCB files, may or may not be suitable for any other purposes. If used, the design material becomes your responsibility as to whether or not it meets your specific needs or your specific applications and may require changes to meet your requirements.
BeagleBoard.org Foundation and logo-licensed manufacturers (together, henceforth identified as "Supplier") provide BeagleBone AI under the following conditions:
The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies Supplier from all claims arising from the handling or use of the goods.
Should BeagleBone AI not meet the specifications indicated in the System Reference Manual, BeagleBone AI may be returned within 90 days from the date of delivery to the distributor of purchase for a full refund. THE FOREGOING LIMITED WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY SELLER TO BUYER AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE. EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.
Please read the System Reference Manual and, specifically, the Warnings and Restrictions notice in the Systems Reference Manual prior to handling the product. This notice contains important safety information about temperatures and voltages.
No license is granted under any patent right or other intellectual property right of Supplier covering or relating to any machine, process, or combination in which such Supplier products or services might be or are used. The Supplier currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive. The Supplier assume no liability for applications assistance, customer product design, software performance, or infringement of patents or services described herein.
BeagleBone AI is not a complete product. It is intended solely for use for preliminary feasibility evaluation in laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application risks associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a finished end product.
You acknowledge, represent, and agree that:
-
You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees, affiliates, contractors or designees) of BeagleBone AI for evaluation, testing and other purposes.
-
You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates, contractors or designees, using BeagleBone AI. Further, you are responsible to assure that any interfaces (electronic and/or mechanical) between BeagleBone AI and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to minimize the risk of electrical shock hazard.
-
Since BeagleBone AI is not a completed product, it may not meet all applicable regulatory and safety compliance standards which may normally be associated with similar items. You assume full responsibility to determine and/or assure compliance with any such standards and related certifications as may be applicable. You will employ reasonable safeguards to ensure that your use of BeagleBone AI will not result in any property damage, injury or death, even if BeagleBone AI should fail to perform as described or expected.
It is important to operate BeagleBone AI within Supplier’s recommended specifications and environmental considerations per the user guidelines. Exceeding the specified BeagleBone AI ratings (including but not limited to input and output voltage, current, power, and environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact the Supplier representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to BeagleBone AI and/or interface electronics. Please consult the System Reference Manual prior to connecting any load to BeagleBone AI output. If there is uncertainty as to the load specification, please contact the Supplier representative. During normal operation, some circuit components may have case temperatures greater than 60 C as long as the input and output are maintained at a normal ambient operating temperature. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using BeagleBone AI’s schematic located at the link in BeagleBone AI’s System Reference Manual. When placing measurement probes near these devices during normal operation, please be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable in electronic measurement and diagnostics normally found in development environments should use BeagleBone AI.
You agree to defend, indemnify and hold Supplier, its licensors and their representatives harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in connection with any use of BeagleBone AI that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims arise under law of tort or contract or any other legal theory, and even if BeagleBone AI fails to perform as described or expected.
If you intend to evaluate the components for possible use in safety critical applications (such as life support) where a failure of the Supplier’s product would reasonably be expected to cause severe personal injury or death, such as devices which are classified as FDA Class III or similar classification, then you must specifically notify Supplier of such intent and enter into a separate Assurance and Indemnity Agreement.
