2.1.1.1 Power Supply

HSEC adapter board utilizes the power from the SOM board provided by the PMIC to supply the EtherCAT PHYs and EEPROM and other components on the board.

The figure below shows the distribution of power to various.

The following sections describe the power distribution network topology that supplies the HSEC board, supporting components, and reference voltages.

The HSEC adapter board is the input 5V source for the SOM board which is provided by the docking station. The 5V is then transferred as input to the SOM through a high-density connector, which utilizes this input to generate the powers that go to the HSEC board through a high-density connector. The HSEC adapter board gets 3V3 input from the PMIC and this is the input for the EtherCAT PHY’s and EEPROM.
