8.3.8.2 Output Detection

When any output is in on status (the corresponding Data Register bit is set to ‘1’), if the current goes through any output is sensed to be lower than IOS_th mA, then an open load condition or short to ground fault is reported to the fault register while the output does not close automatically.

For the inductive load, during the on status of any output, TI recommends to read the fault regs two times. Because the inductive load leads to error detection results and it needs ignore the first time readout results during the set up process of the output current, TI recommends to read the fault regs again after the current through the load is stable.
