LM5060: LM5060 Max Vin rating

Part Number: LM5060
Other Parts Discussed in Thread: LM74800-Q1

Team,

A customer is using LM5060 as a high side switch, with maximum operating voltage as 55V. However, they have a test for transients that requires the Vin to be 70V for ~40ms, while the device is enabled. The data sheet however mentions the absolute max rating for Vin = 75V only when device is disabled. Can you please clarify why this is so and can they use this device in their application?
