8.3.2 Short-Circuit Duration

The INA254 features a physical shunt resistance that is able to withstand current levels higher than the continuous handling limit of 50 A without sustaining damage to the current-sensing resistor or the current-sensing amplifier, if the excursions are brief. Figure 8-2 shows the short-circuit duration curve for the INA254.
