Short-to-Input has the same detection mechanism and behavior as open-load detection, in both the on-state and off-state. See Table 8-3 for more details.

In the on-state, reverse current flows through the FET instead of the body diode, leading to less power dissipation. Thus, the worst case occurs in the off-state.

• If V_OUTx – V_IN < V_F (body diode forward voltage), no reverse current occurs.
• If V_OUTx – V_IN > V_F, reverse current occurs. The current must be limited to less than I_R1. Setting an ENx pin high can minimize the power stress on its channel. Also, for external reverse protection, see Reverse-Current Protection for more details.
