2.3.1 Power Requirements

AM62x-Low Power SK EVM can be powered through either of the two USB Type C Connectors –

  • Connector 1(J13) - Power role – SINK, No Data role
  • Connector 2(J15) - Power role – DRP, Data role – USB2.0 DFP or UFP

The AM62x-Low Power SK EVM supports voltage input ranges of 5V - 15V and 3A 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, it 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 will be selected to power the board.

Table 2-1 Type-C port Power roles
J13(UFP) J15(DRP) BoardPower Remarks
Plugged in NC ON - J13 J13 will be UFP and will only sink power & J15 can act as DFP if a peripheral is connected
NC Plugged in ON - J15 J15 will be UFP and can only sink power
Plugged in Plugged in ON- J13 or J15 Board will be 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 it can negotiate a power contract with a compatible power source.

The configuration file is loaded to the EEPROM using header J23. 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.

Power indication LEDs are provided for both the Type-C connectors for the user to identify which connector is powering the SKEVM Board. An external power supply (Type-C output) can be used to power the EVM but is not included as part of the SKEVM kit.

Note: Minimum Voltage: 5VDC, Recommended Minimum Current: 3000mA, Maximum Voltage: 15VDC, Maximum current: 5000mA. Because SK-AM62-LP 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, as such, if the power supply exceeds the maximum voltage and current requirements listed above is acceptable as long as the power adapter is compliant with the USB-C PD specification.

(*) This is the adapter part number used for compliance testing.

Note: TI recommends using an external power supply or power accessory which complies with applicable regional safety standards such as (by example) UL, CSA, VDE, CCC, PSE, etc.
