The device contains an open-drain output that signals an interrupt and is valid only after the device has completed start-up into a valid state. If the part starts into a fault, interrupts will not be sent. The INT pin is normally in high impedance and is pulled low for 128us when an interrupt condition occurs. When a fault or status change occurs or any other condition that generates an interrupt such as ADC DATA READY, a 128us pulse (interrupt) is sent on INT to notify the host. All interrupts may be masked through I2C. If the interrupt condition occurs while the interrupt is masked an interrupt pulse will not be sent. If the interrupt is unmasked while the fault condition is still present, an interrupt pulse will not be sent until the INT trigger condition occurs while unmasked.
