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

1 When V_PS is less than V_PSF the flag pin indicates low protection supply voltage. Refer to TRUTH TABLE.
2 The drain source current which flows in a normal load when the protection supply is high and the input is low.
3 If V_DS < V_DSF then the flag indicates open circuit load.
4 For open circuit load detection, V_IS must be less than V_ISF.
5 Trip time t_{d sc} varies with overload dissipation P_D according to the formula t_{d sc} ≈ T_DSC / ln[ P_D / P_D(TO)].
