Figure 8-31. FLT Pin Behavior With an Overcurrent Event on Channel Enable
Figure 8-32 shows the device fault and retry behavior when there is a slow creep into an over-current event. As
shown, the switch clamps the current until it hits thermal shutdown, and then the device will remain latched off
until the AUTO_RETRY_DIS bit is low.
