2.1.2 USB PD shield board
Figure 2. USB PD shield board
2.2 Shield board description
Please refer to
Figure 1
and
Figure 2
above for the actual shield board block diagram
and image. It consists of 4 Arduino headers, 2 on either side of the board. J403, J404
on the left and J405, J9 on the right side. These Arduino headers mate with the Kinetis
KL27Z Freedom board. The shield board is powered by a 9V Power Adaptor. The board
has the below power regulators.
1. 5V switching regulator.
2. A 3.3V switching regulator to power up the PD PHY and circuitry on the board.
3. A 1.8V LDO to power up circuitry on the board.
The board supports both USB-PD PHY PTN5110 and a CCLogic chip, PTN5150A. The
CC lines from Type C connector are connected to one of these chips depending on
the jumper options we select. There is a secure Authentication chip A1006 which can
be used for authenticating the devices/ Chargers plugged into the TypeC Connector.
Currently the Kinetis USB-PD SDK does not support Authentication. But the hardware
can be used to test out any authentication SW implemented by end user.
