Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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:
DC current is also limited by the thermal design of the system.
Note 2:
Junction temperature greater than +125°C degrades operating lifetimes.

Note that a “+”, “#”,
or “-” in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains
to the package regardless of RoHS status.
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.

Note 3:
All units are 100% production tested at T
A
= +25NC. Limits over the operating temperature range are guaranteed by
design and characterization; not production tested.
Note 4:
Not production tested, user settable. See overvoltage/undervoltage lockout instructions.
Note 5:
The current limit can be set below 700mA with a decreased accuracy.
Note 6:
All timing is measured using 20% and 80% levels.
Note 7:
The ratio between the autoretry time and blanking time is fixed and equal to 30.
