7.4 VINx Collapse Rate

The LM66200 uses the highest voltage supply to power the device. When one supply drops below the other, the device changes the supply used to power the device. If the supply powering the device drops at a rate faster than 1 V/10 μs, the other supply must be at 2.5 V or higher to prevent the device from resetting. If the other supply is lower than 2.5 V, then the device is not be able to switch to the supply quickly enough, and the device resets and turns on with soft start timing. To slow down the decay of the input, capacitance can be added to the input or output.
