CC Line Capacitance

USB PD has a specification for the total amount of capacitance that is required for proper USB PD BMC operation on the CC lines. The specification from section 5.8.6 of the USB PD Specification is given below in Table 4.

Table 4. USB PD cReceiver Specification

NAME DESCRIPTION MIN MAX UNIT COMMENT
cReceiver CC receiver capacitance 200 600 pF The DFP or UFP system shall have capacitance within this range when not transmitting on the line

Therefore, the capacitance on the CC lines must stay in between 200 pF and 600 pF when USB PD is being used. Therefore, the combination of capacitances added to the system by the TPS65982, the TPD6S300A, and any external capacitor must fall within these limits. Table 5 shows the analysis involved in choosing the correct external CC capacitor for this system, and shows that an external CC capacitor is required.

Table 5. CC Line Capacitor Calculation

CC Capacitance MIN MAX UNIT COMMENT
CC line target capacitance 200 600 pF From the USB PD Specification section
TPS65982 capacitance 70 120 pF From the TPS65982 Datasheet
TPD6S300A capacitance 60 120 pF From the Electrical Characteristics table.
Proposed capacitor GRM033R71E221KA01D 110 330 pF CAP, CERM, 220 pF, 25 V, ±10%, X7R, 0201 (For min and max, assume ±50% capacitance change with temperature and voltage derating to be overly conservative)
TPS65982 + TPD6S300A + GRM033R71E221KA01D 240 570 pF Meets USB PD cReceiver specification
