(1)

All the protections have a recovery delay time. The recovery timer starts as soon as the fault is triggered. The device will start to check

for recovery condition only when the recovery timer expires. This is NOT a delay time between recovery condition to FETs recovery.

OVP recovery delay = 12ms; UVP/OCC/OCD recovery delay = 8ms.
