The value of 4.25 mA for I
CC
in
the previous equation was
obtained by derating the I
CC
max
of 5 mA (which occurs at -40
°
C)
to I
CC
max at 90
°
C (see Figure 7).
Since P
O
for this case is greater
than P
O(MAX)
, Rg must be
increased to reduce the HCPL-
3150 power dissipation.

Thermal Model
The steady state thermal model
for the HCPL-3150 is shown in
Figure 28. The thermal resistance
values given in this model can be
used to calculate the tempera-
tures at each node for a given
operating condition. As shown by
the model, all heat generated
flows through
θ
CA
which raises
the case temperature T
C
accordingly. The value of
θ
CA
depends on the conditions of the
board design and is, therefore,
determined by the designer. The
value of
θ
CA
= 83
°
C/W was
obtained from thermal measure-
ments using a 2.5 x 2.5 inch PC
board, with small traces (no
ground plane), a single HCPL-
3150 soldered into the center of
the board and still air. The
absolute maximum power
dissipation derating specifications
assume a
θ
CA
value of 83
°
C/W.
Inserting the values for
θ

θ

shown in Figure 28 gives:

C/W:
shown in Figure 29. The HCPL-
3150 improves CMR performance
by using a detector IC with an
optically transparent Faraday
shield, which diverts the capaci-
tively coupled current away from
the sensitive IC circuitry. How
ever, this shield does not
eliminate the capacitive coupling
between the LED and optocoup-
ler pins 5-8 as shown in
Figure 30. This capacitive
coupling causes perturbations in
the LED current during common
mode transients and becomes the
major source of CMR failures for
a shielded optocoupler. The main
design objective of a high CMR
LED drive circuit becomes
keeping the LED in the proper
state (on or off) during common
mode transients. For example,
the recommended application
circuit (Figure 25), can achieve
15 kV/
μ
s CMR while minimizing
component complexity.
Techniques to keep the LED in
the proper state are discussed in
the next two sections.
From the thermal mode in Figure
28 the LED and detector IC
junction temperatures can be
expressed as:

Considerations for Ultra
High CMR Performance
Without a detector shield, the
dominant cause of optocoupler
CMR failure is capacitive
coupling from the input side of
the optocoupler, through the
package, to the detector IC as
