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 +25
°
C. Electrical limits across the full temperature range are guaranteed by design and correlation.
Note 2:
Latch-off current does not include the current flowing into
FLAG
.
Note 3:
TDFN packages are guaranteed by design.
Note 4:
The on-time is defined as the time taken for the current through the switch to go from 0mA to full load. The off-time is defined as
the time taken for the current through the switch to go from full load to 0mA.
Note 5:
Retry time is typically 15 times the blanking time.
