PRODUCTION DATA
The TPS2583x-Q1 is a Type-C controller that supports all Type-C functions in a downstream facing port. It is also used to manage current advertisement and protection to a connected UFP and active cable. When VIN 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 buck regulator turn-ons after the required de-bounce time is met. If connected, the LS_GD pin sources current into the external MOSFET allowing current to flow from CSN/OUT to BUS. If Ra is detected on the other CC pin (not connected to UFP), VCONN is applied to allow current to flow from VCC to the CC pin connected to Ra. For a complete listing of various device operational modes refer to Table 10-7.
The TPS2583x-Q1 always starts in Type-C mode, then transitions to DCP, CDP, or SDP as determined by the CTRL1 and CTRL2 pins and signaling by the connected portable device on the DP_IN and DM_IN pins.
