Programming Overcurrent Protection
Overcurrent protection guards the load against output currents that reach a
specified value greater than the programmed protection level. It is
accomplished by programming the output current to zero.
The following steps show how to set the overcurrent protection trip level, how
to check OCP operation and how to clear overcurrent condition.
