VPHY_OVPOVP detection threshold for USB PD PHY0V ≤ VVIN_3V3 ≤ 3.6V, 0V ≤ VPP5V ≤ 5.5V, VVBUS ≥ 4V. Initially VCC1 ≤ 5.5V and VCC2 ≤ 5.5V, then VCCx rises5.58.5V
Receiver
ZBMCRXReceiver input impedance on CCyDoes not include pullup or pulldown resistance from cable detect. Transmitter is Hi-Z1MΩ
CCCReceiver capacitance on CCy1Capacitance looking into the CC pin when in receiver mode120pF
VRX_SRC_R Rising threshold on CCy for receiver comparator Source mode (rising) 784 825 866 mV
VRX_SRC_F Falling threshold on CCy for receiver comparator Source mode (falling) 523 550 578 mV
(1) CCC includes only the internal capacitance on a CCy pin when the pin is configured to be receiving BMC data. External capacitance is needed to meet the required minimum capacitance per the USB-PD Specifications (cReceiver). Therefore, TI recommends adding CCCy externally.
