Hello,

It looks like if you set the OLD_OP bit in the OLD_CTRL_2 register to 1, then OUTX pins stay in their previous state and do not react to the OLD fault unless the user takes action. Similarly, the OLD_REP bit determines if the OLD fault will report on the nFAULT pin or only in the IC_STAT register. Table 8 summarizes the open-load detection feature and conditions.  The OLD control registers (OLD_CTRL_1 and OLD_CTRL_2) allow the user to disable OLD on the OUTX pins with the HBX_OLD_DIS bits

Look through pages 46 and 47 in the datasheet and see if that works for you.

Jacob T.
