TPS2546 adopts DCP_Auto mode, and the maximum current setting is about 2.3A. When charging, the 5V of Pin 12 will jump to 0, and then immediately recover. What is the reason for this?

Hi Emma,
Hello,
This is a native part of the DCP_auto mode. If you do not want this behavior, please try a different mode, such as CDP or DCP_shorted, listed in the Table 3 truth table.
Thanks,
Emma
