2.19.1 Power Requirements

AM62x SIP SKEVM can be powered through either of the two USB Type C Connectors:

  • Connector 1 (J11) - Power role – SINK, No Data role
  • Connector 2 (J13) - Power role – DRP, Data role – USB2.0 DFP or UFP

The AM62x SIP SK EVM supports voltage input ranges of 5 V - 15 V and 3 A of current. A USB PD controller Mfr.Part# TPS65988DHRSHR is used for PD negotiation upon cable detection to get necessary power required for the board. Connector 1 is configured to be an UFP Port and has no Data role. Connector 2 is configured as a DRP port and can act as DFP only when the board is being powered by Connector 1. When both the connectors are connected to external power supply, the port with highest PD power contract is selected to power the board.

Table 2-11 Type-C Port Power Roles
J11(UFP) J13(DRP) Board Power Remarks
Plugged in NC ON- J11 J11is UFP and only sinks power and J13 can act as DFP if a peripheral is connected.
NC Plugged in ON - J13 J13 is UFP and can only sink power.
Plugged in Plugged in ON- J11 or J13 Board is powered by the port with highest PD power contract.

The PD IC uses a SPI EEPROM to load the necessary configuration on power up so the PD IC can negotiate a power contract with a compatible power source.

The configuration file is loaded to the EEPROM using header J22. Once the EEPROM is programmed the PD obtains the configuration files via SPI communication. Upon loading the configuration files the PD negotiates with the source to obtain the necessary power requirement.

Note: The EEPROM is pre-programmed with the configuration file for the operation of the PD controller.

Power indication LEDs are provided for both the Type-C connectors for the user to identify which connector is powering the SK EVM Board.

An external power supply (Type-C output) can be used to power the EVM but is not included as part of the SK EVM kit.

The external power supply requirements (Type-C) are:

Minimum Voltage: 5 VDC, Recommended Minimum Current: 3000 mA

Maximum Voltage: 15VDC, Maximum current: 5000 mA

Q1251-ND Qualtek QADC-65-20-08CB
Note: Because SK-AM62 SIP implements USB PD for power, the device is able to negotiate to the highest Voltage/Current combination supported by both the Device and Power Adapter. If the power supply exceeds the maximum voltage and the current requirements listed above are acceptable, then the power adapter is compliant with the USB-C PD specification.
