For the CYPD4155-96BZXI, what are the VOL and VOH specifications on the VBUS FET control output pins (VBUS_P_CTRL_P1 and VBUS_C_CTRL_P1) ? Similarly, what are the VOL and VOH specifications on VBUS_DISCHARGE_P1 and OVP_TRIP_P1? Do the specifications SID.GIO#33-#36 in the EZ-PD™ CCG4M manual (Document Number 002-11084 Rev. *C) apply to these pins in this mode (see attached)?
What is the UVP threshold on VCONN_MON_P1?
Finally, regarding VBUS_P_CTRL_P1 and VBUS_C_CTRL_P1 with the firmware that is shipped from the factory in the IC, are these signals active-low or active-high?
Thanks, Hal

Hello Hal,
Here is the answer to your last question:
Q3)Regarding VBUS_P_CTRL_P1 and VBUS_C_CTRL_P1 with the firmware that is shipped from the factory in the IC, are these signals active-low or active-high?
A) CYPD4155-96BZXI is shipped with CYPD4225-40LQXI_i2c_boot_0_0_0_58_0_0_0_nb.hex firmware inside.
In config.h of said firmware, we can see the following macros:
/* Function/Macro to turn power source for P1 ON. */
#define APP_VBUS_SRC_FET_ON_P1() VBUS_P_CTRL_P1_Write(1)
/* Function/Macro to turn power source for P1 OFF. */
#define APP_VBUS_SRC_FET_OFF_P1() VBUS_P_CTRL_P1_Write(0)
/* Function/Macro to turn consumer FET for P1 ON. */
#define APP_VBUS_SNK_FET_ON_P1() VBUS_C_CTRL_P1_Write(0)
/* Function/Macro to turn consumer FET for P1 OFF. */
#define APP_VBUS_SNK_FET_OFF_P1() VBUS_C_CTRL_P1_Write(1)
Therefore we can conclude that VBUS_P_CTRL_P1 is active high and VBUS_C_CTRL_P1 is active low.
Best regards,
Pablo
