SW Set: UCLO_EN =1;RIPPLE_THRS = 0X0;SR = 0X4

The configuration about drive hold current of typically value is 0.6A, minimum is 0.53A

According to the SW set, the output Hi-Z limit value is 0.53*68% = 0.36A

Test result of ripple of current of LSD below 0.36A, but do not output Hi-Z, how to guarantee the LSD do not output Hi-Z for all PCBAs of life cycle.
