PRODUCTION DATA
The TPS2585x-Q1 is a Type-C controller that supports all Type-C functions in a downstream facing port. The TPS2585x-Q1 is also used to manage current advertisement and protection to a connected UFP and active cable. When VSENSE exceeds the undervoltage lockout threshold, the device samples the EN pin. A high level on this pin enables the device and normal operation begins. Having successfully completed its start-up sequence, the device now actively monitors its CC1 and CC2 pins for attachment to a UFP. When a UFP is detected on either the CC1 or CC2 pin the USB power switch turn-ons. If Ra is detected on the other CC pin (not connected to UFP), VCONN is applied to allow current to flow to the CC pin connected to Ra.
