Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Note 1:
All parts are 100% tested at T
A
= +25°C. Limits at T
A
= -40°C to +85°C are guaranteed by design.
Note 2:
Latchoff current does not include the current flowing into
FFLG
and
NOLD.
Note 3:
Turn-on time is defined as the time taken for the current through the switch to go from 0mA to full load. Turn-off time is
defined as the time taken for the current through the switch to go from full load to 0mA.
Note 4:
Retry time is typically 14x the blanking time.
