2.1.6.15.1 Power Requirements

AM62x SKEVM can be powered through either of the two USB Type-C™ Connectors. Table 2-13 lists the descriptions of each connector.

Table 2-13 Connector Description
Connector Name Power Role Data Role
Connector 1 (J11) SINK None
Connector 2 (J13) DRP USB2.0 DFP or UFP

The AM62x SK EVM supports voltage input ranges from 5V to 15V and 3A of current. A USB PD controller (manufacturer part number: 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, but connector 2 can only act as DFP when connector 2 powers the board. When both the connectors are connected to external power supply, the port with highest PD power contract powers the board.

Table 2-14 Type-C Port Power Roles
J11 (UFP) J13 (DRP) Board Power Remarks
Plugged in NC ON - J11 J11 becomes UFP and only sinks power and J13 can act as DFP if a peripheral is connected
NC Plugged in ON - J13 J13 becomes UFP and can only sink power
Plugged in Plugged in ON - J11 or J13 The port with highest PD power contract powers the board

The PD IC uses a SPI EEPROM to load the necessary configuration on power up to 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 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.

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

  • Minimum Voltage: 5VDC, Recommended Minimum Current: 3000mA
  • Maximum Voltage: 15
  • VDC, Maximum current: 5000mA
Table 2-15 Recommended External Power Supply
DigiKey Part Number Manufacturer Manufacturer Part Number
1939-1794-ND GlobTek™, Inc. TR9CZ3000USBCG2R6BF2
Q1251-ND Qualtek™ QADC-65-20-08CB
Note: Because SK-AM62 implements USB PD for power, the device negotiates to the highest voltage and current combination supported by the device and power adapter. If the power adapter is compliant with the USB-C PD specification, the power supply can exceed the maximum voltage and current requirements listed above.
