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.
