(10) 1.5 A DFP mode is active after a USB Power Delivery contract has been negotiated. (11) 3 A DFP mode is active after GDNG has been enabled until a USB Power Delivery message is received. (12) VCONN is always applied when a UFP is attached, regardless of whether Ra is detected. (13) The VCONN pin has reverse blocking. (14) Based on 120 mV drop at 250 mA (to deliver more than 1 W at VCONN = 4.75 V). (15) There are requirements for the VCONN voltage supplied to CC1 or CC2 in [1]; customers need to take the RDSON into account when designing to meet those requirements. (16) While providing VCONN power, the CCx output is monitored for faults (overloads). Thermal shutdown is provided with thermal cycling (auto-restart). Amplitude of interference that can be tolerated. Interference is 600 kHz square wave, rising 0 to 100 mV. 100 mV Interference is 1 MHz sine wave 1 VPP DFP Specifications (CC1, CC2) VDSTD Detach threshold when cable is detached while in standard DFP mode.
