I have a question about LTC4291-1 & LTC4292.
I am checking if the LTC4292 can be connected to the evaluation board (DC2911A) set to Class 8 of the LT4293 to supply power.
In Auto mode, power was supplied without problems when a Class 8 PD was connected to Port 1 and Port 2.
In semi-automatic mode, Port1 was able to supply power with Class8 without any problem.
However, if you continue to connect DC2911A to Port2, it will be judged as Class4 by PSE even though it is set to Class8.
At that time, the voltage was output only to OUT2A, and the voltage was not output from OUT2B.
Is there any possible cause?
When using in semi-automatic mode, PCUTn, CUTn, and LIMn are set so that Class 8 can be output.
Also, if Port2 is connected first, Port2 will be powered by Class8 and Port1 will be judged by Class4.
I would appreciate it if you could reply.
