SPEC: 

The CCG5 has power supply inputs at V5V_P1 and V5V_P2 pins for providing power to EMCA cables through
integrated VCONN FETs. There are two VCONN FETs in CCG5 per Type-C port to power CC1_P1/P2 and
CC2_P1/P2 pins. These FETs can provide a minimum of 1.5 W on the CC1 and CC2 pins for EMCA cable

(1). if V5V_P1 is 5V,

does it mean the Vconn Source is 1.5W / 5V = 0.3A ?

and configuaration - Vconn OCP setting is threshold = 30% , Debouce period = 1ms 

does it mean Vconn OCP trigger point is 0.3A x 1.3 = 0.39A and debouce = 1ms 

(1). if V5V_P1 is 3.3V ,

does it mean the Vconn Source is 1.5W / 3.3V = 0.4545A ?

and configuaration - Vconn OCP setting is threshold = 30% , Debouce period = 1ms 

does it mean Vconn OCP trigger point is 0.4545A x 1.3 = 0.59A and debouce = 1ms

but SEPC :

In a notebook design, VCONN supplies power to the electronically marked cable attached to it. VCONN FETs on
CC lines can handle a current up to 0.5 A

it mean max vocnn ocp trigger point is 0.5A ??

Hi ,

Thank you for creating a post in infineon developer community.

 As per the Data sheet, V5V_P1 & V5V_P2 could not able to support 3.3v 

HmdRahmathulla_0-1660213256199.png

it is correct for 5v and threshold of 30% is  = 0.39Amp of OCP and Debouce period is 1ms as per the configuration

 

please refer below table for min and max of OCP
