Hello, experts.

DIAG Register (Offset = 7Bh) [Reset = X] In what scenario does the IRETRY parameter of this Register need to be modified, will it affect the accuracy of open circuit detection and short circuit detection? Please let us know;

Lin,

Some users might not expect LED blink or seem bright during Iretry and hope it can be configurable.

Open circuit/short circuit detection monitors Supply - Vout and Vout- GND differential voltage. As long as the voltage difference triggers threshold when fault happens, it is ok.
