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.

All devices are 100% production tested at TJ = +25°C and +125°C. Limits to -40°C are guaranteed by design.
Guaranteed by design, not production tested.
Parameter is measured at trip point of latch with VFB = 0V.
Gain is defined as A = ΔVCOMP / ΔVCS, 0.05V ≤ VCS ≤ 0.25V.
See Figures 3 and 4.
A 65Ω pullup resistor is connected from OUT_ to 5.5V. Rising refers to VOUT_ when current through OUT_ is turned off and
falling refers to VOUT_ when current through OUT_ is turned on.
