Datasheet

Note 1: This device is 100% production tested at T
J
= +25°C and +125°C. Limits to -40°C are guaranteed by design.
Note 2: Guaranteed by design, not production tested.
Note 3: Parameter is measured at trip point of latch with V
FB
= 0V.
Note 4: Gain is defined as A = ∆VCOMP/∆VCS, 0.05V ≤ VCS ≤ 0.25V.
Note 5: See Figures 3 and 4.
Note 6: A 65Ω pullup resistor is connected from OUT_ _ to 5.5V. Rising refers to V
OUT_ _
when current through OUT_ _ is turned off
and falling refers to V
OUT_ _
when current through OUT_ _ is turned on.
(V+ = +3V to < +4.5V, AGND = PGND = 0V; all voltages are measured with respect to PGND, unless otherwise noted. T
A
= T
J
=
-40°C to +125°C, unless otherwise noted. Typical values are at T
A
= +25°C.) (Notes 1, 5)
