How do I protect TPS73601DRB from a sudden loss of power? The specific concern is when a short-circuit forces the input voltage to zero. Application is +5V input, +4.7V output, approx 10uF total output capacitance. I chose this part based on the specsheet headline and description, then later found this detail on page 14: "... the EN pin must be driven low before the input voltage is removed. If this is not done, the pass element may be left on due to stored charge on the gate." So, to have reverse current protection it seems that the EN pin must be driven low in anticipation of the fault condition.
My concern is to avoid damage to the TPS73601DRB when input short-circuit occurs. The specsheet claims internal current limit protects the device from short-circuit. If this protection includes reverse current, then all is well. If not, then ... ideas?
