OPEN CIRCUIT LOAD DETECTION CHARACTERISTICS
An open circuit load condition can be detected while the TOPFET is in the off-state.

For protection ‘0’ equals low, ‘1’ equals high.
For input ‘0’ equals low, ‘1’ equals high, ‘X’ equals don’t care.
For flag ‘0’ equals low, ‘1’ equals open or high.
For output switch ‘0’ equals off, ‘1’ equals on.
1 The drain source current which flows when the protection supply is high and the input is low.
2 For open circuit load indication, V_IS must be less than V_ISF.
