Texas Instruments TPS25730 - 2.7.3 Sink Current Configuration

2.7.3 Sink Current Configuration
The sink current is configured according to Table 2-9. The configuration sets Operating and Maximum Current
in the USB PD request message. The Operating Current is defined as the the current required for the sink to
be functional. The Maximum Current is defined as the maximum current the sink can use. The Operating and
Maximum Current can be the same if the Operational Current is the maximum current required for the sink to
be functional. The Capabilities Mismatch bit is set when the PD Source Capabilities do not meet the Operating
Current. When the Operating Current is set to 0 A the Capability Mismatch bit is not set.
