APPLICATIONS INFORMATION
Thedesiredtrippointsandfull-scaleanalogoutputvoltage
for the circuit in Figure 13 can be achieved as follows:
R1
=
400mV
IOVER
R2
=
VMAX –IMAX R1
( )
IMAX
R3
=
400mV – IUNDER R1+ R2
(
)
IUNDER
Trip points for the LT6109-2 can be set by replacing IUNDER
with a second overcurrent, IOVER2.
Hysteresis
Each comparator has a typical built-in hysteresis of 10mV
to simplify design, ensure stable operation in the pres-
ence of noise at the inputs, and to reject supply noise that
might be induced by state change load transients. The
hysteresis is designed such that the threshold voltage is
altered when the output is transitioning from low to high
as is shown in Figure 12.
External positive feedback circuitry can be employed
to increase the effective hysteresis if desired, but such
circuitry will have an effect on both the rising and fall-
ing input thresholds, VTH (the actual internal threshold
remains unaffected).
Figure 13 shows how to add additional hysteresis to a
noninverting comparator.
R6canbecalculatedfromtheextrahysteresisbeingadded,
VHYS(EXTRA) and the amplifier output current which you
want to cause the comparator output to trip, IUNDER. Note
that the hysteresis being added, VHYS(EXTRA),isinaddition
to the typical 10mV of built-in hysteresis.
R6
=
400mV – VHYS(EXTRA)
IUNDER
R1 should be chosen such that R1 >> R6 so that VOUTA
does not change significantly when the comparator trips.
