CMR with the LED On
(CMR
H
).
A high CMR LED drive circuit
must keep the LED on during
common mode transients. This is
achieved by overdriving the LED
current beyond the input
threshold so that it is not pulled
below the threshold during a
transient. A minimum LED cur-
rent of 10 mA provides adequate
margin over the maximum I
FLH
of
5 mA to achieve 15 kV/
μ
s CMR.
CMR with the LED Off
(CMR
L
).
A high CMR LED drive circuit
must keep the LED off (V
F
≤
V
F(OFF)
) during common mode
transients. For example, during a
-dV
cm
/dt transient in Figure 31,
the current flowing through C
LEDP
also flows through the R
SAT
and
V
SAT
of the logic gate. As long as
the low state voltage developed
across the logic gate is less than
V
F(OFF)
, the LED will remain off
and no common mode failure will
occur.
The open collector drive circuit,
shown in Figure 32, cannot keep
the LED off during a +dVcm/dt
transient, since all the current
flowing through C
LEDN
must be
supplied by the LED, and it is not
recommended for applications
requiring ultra high CMR
L
performance. Figure 33 is an
alternative drive circuit which,
like the recommended application
circuit (Figure 25), does achieve
ultra high CMR performance by
shunting the LED in the off state.
