DRV8801 Overcurrent Limit

The DRV8801 datasheet describes an overcurrent  trip feature - if the voltage on the current sense resistor goes above 0.5V, the drivers are disabled.

Can anyone tell me some details of its operation?

• Is this the same as the Overcurrent protection or in addition to it?
• Does the nFault output go low when triggered?
• Does the output turn on again after a delay period?

Thanks!
