Over-Current Event

Figure 3-4 and Figure 3-5 show the overcurrent response of LM5066I hot-swap controller captured on the PMP23496 reference design.

PMP23496 Over-Current Event (Captured Signals:
            VIN, VOUT, TIMER, and IIN): VIN = 54V, ILIM = About 150A (Current limit threshold = 50mV
          and Effective RSNS = 330µΩ), and TFLT = 520µs Figure 3-6 Over-Current Event (Captured Signals: VIN, VOUT, TIMER, and IIN): VIN = 54V,
ILIM = About 150A (Current limit threshold = 50mV and Effective RSNS = 330µΩ), and TFLT = 520µs
PMP23496 Over-Current Event (Captured Signals:
            VOUT, HS GATE, FET GATE, and IIN): VIN = 54V,
            ILIM = About 150A (Current limit threshold = 50mV and Effective
            RSNS = 330µΩ), and TFLT = 520µs Figure 3-7 Over-Current Event (Captured Signals: VOUT, HS GATE, FET GATE, and IIN): VIN = 54V, ILIM = About 150A (Current limit threshold = 50mV and Effective RSNS = 330µΩ), and TFLT = 520µs
