2.3.5 nINTO (Interrupt Output) Pin

Pin nINTO is an active-low, open-drain Interrupt output pin. The nINTO pin goes low every time a fault is detected, and the corresponding Interrupt masking bit is cleared.

By default, all Interrupt generating events are masked (xxxMSK bits are “1” by default) and the end user needs to unmask those to enable Interrupt generation on faults.

Only one Interrupt generation event is always enabled and cannot be disabled. The Enable (EN) timeout described in section Typical Power-Down Sequence and Timing also shows this.
