7.3.2 Short-Circuit Duration

The INA250-Q1 features a physical shunt resistance that can withstand current levels higher than the continuous handling limit of 15 A without sustaining damage to the current-sensing resistor or the current-sensing amplifier if the excursions are brief.  Figure 7-2 shows the short-circuit duration curve for the INA250-Q1.
