In section 10.4.1 (Control of VBUS Provider Path and VBUS Consumer Path) of the Hardware Design Guidelines for the DRP Applications Using EZ-PD USB Type-C Controllers (AN210403), the circuitry shows a series of transistors without any list of specific components. What are the actual components for Q1, Q5, Q6, and Q16 on this page?
Thanks,
Hal

Hi Hal,
Yes, the firmware for CYPD4225 is specific to the CY4541 EVK hardware and hence VBUS_P_CTRL_P1 is active high but VBUS_C_CTRL_N_P1 is active low. If you want these to be configured differently, please refer to config.h and pdss_hal.c files in the firmware as these are set using the pd_internal_pfet_on(), pd_inetrnal_cfet_on() APIs.
For CCG4M firmware examples, you could refer to the KBA since they arent included in the Host SDK.
Best Regards,
Sananya
