8.3.7.2 Overcurrent Output Response

Figure 8-8 shows the active-low overcurrent digital output OC response to bidirectional overcurrent events. When the input current exceeds |±IOC| on a bidirectional device, the fast OC pin is pulled low. The input current must return to within ±IOC by more than a hysteresis current IHys before the OC pin resets back to the normal high-state.
