HCPL-315J
Description
The HCPL-315X consists of a LED
optically coupled to an integrated
circuit with a power output stage.
This optocoupler is ideally suited
for driving power IGBTs and
MOSFETs used in motor control
inverter applications. The high
operating voltage range of the
output stage provides the drive
voltages required by gate
controlled devices. The voltage
and current supplied by this
optocoupler makes it ideally
suited for directly driving IGBTs
with ratings up to 1200 V/50 A.
For IGBTs with higher ratings, the
HCPL-3150/315J can be used to
drive a discrete power stage
which drives the IGBT gate.

Applications Information
Eliminating Negative IGBT Gate
Drive
To keep the IGBT firmly off, the
HCPL-3150/315J has a very low
maximum VOL specification of
1.0 V. The HCPL-3150/315J
realizes this very low VOL by
using a DMOS transistor with
4 (typical) on resistance in its
pull down circuit. When the
HCPL-3150/315J is in the low
state, the IGBT gate is shorted to
the emitter by Rg + 4 .
Minimizing Rg and the lead
inductance from the HCPL-3150/
315J to the IGBT gate and
emitter (possibly by mounting
the HCPL-3150/315J on a small
PC board directly above the
IGBT) can eliminate the need for
negative IGBT gate drive in
many applications as shown in
Figure 25. Care should be taken
with such a PC board design to
avoid routing the IGBT collector
or emitter traces close to the
HCPL-3150/315J input as this
can result in unwanted coupling
of transient signals into the
HCPL-3150/315J and degrade
performance. (If the IGBT drain
must be routed near the HCPL-
3150/315J input, then the LED
should be reverse-biased when
in the off state, to prevent the
transient signals coupled from
the IGBT drain from turning on
the HCPL-3150/315J.)

Step 1: Calculate Rg Minimum
from the IOL Peak
Specification. The IGBT and Rg
in Figure 26 can be analyzed as a
simple RC circuit with a voltage
supplied by the
HCPL-3150/315J.

The VOL value of 2 V in the pre-
vious equation is a conservative
value of VOL at the peak current
of 0.6A (see Figure 6). At lower
Rg values the voltage supplied
by the HCPL-3150/315J is not an
ideal voltage step. This results in
lower peak currents (more
margin) than predicted by this
analysis. When negative gate
drive is not used VEE in the
previous equation is equal to
zero volts.
Step 2: Check the HCPL-3150/
315J Power Dissipation and
Increase Rg if Necessary. The
HCPL-3150/315J total power
dissipation (PT) is equal to the
sum of the emitter power (PE)
and the output power (PO):

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

Thermal Model
(HCPL-3150)
The steady state thermal model
for the HCPL-3150 is shown in
Figure 28a. The thermal
resistance values given in this
model can be used to calculate
the temperatures at each node
for a given operating condition.
As shown by the model, all heat
generated flows through qCA
which raises the case
temperature TC accordingly. The
value of qCA depends on the
conditions of the board design
and is, therefore, determined by
the designer. The value of qCA =
83°C/W was obtained from
thermal measurements 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 qCAvalue
of 83°C/W.
From the thermal mode in
Figure 28a the LED and detector
IC junction temperatures can be
expressed as:
TJE = P
E (qLC||(qLD + qDC) + qCA)
qLC qDC
+ PD(——————————— + qCA) + TA
qLC + qDC + qLD
qLC qDC
TJD = PE (—————————— + qCA)
qLC + qDC + qLD
+ P
D(qDC||( qLD + qLC) + qCA) + TA
Inserting the values for qLC and
qDC shown in Figure 28 gives:
TJE = LED junction temperature
TJD = detector IC junction temperature
TC= case temperature measured at the center of the package bottom
qLC = LED-to-case thermal resistance
qLD = LED-to-detector thermal resistance
qDC = detector-to-case thermal resistance
qCA = case-to-ambient thermal resistance
*qCA will depend on the board design and the placement of the part.

TJE = PE313°C/W + PD132°C/W + TA

132°C/W + 70°C = 117°C
TJD = PE132°C/W + PD187°C/W + TA
= 45 mW132°C/W + 250 mW
187°C/W + 70°C = 123°C
TJE and TJD should be limited to
125°C based on the board layout
and part placement (qCA) specific
to the application.

Description
This thermal model assumes
that a 16-pin dual-channel
(SOIC-16) optocoupler is
soldered into an 8.5 cm x 8.1 cm
printed circuit board (PCB).
These optocouplers are hybrid
devices with four die: two LEDs
and two detectors. The
temperature at the LED and the
detector of the optocoupler can
be calculated by using the
equations below.

DTE2A = A21PE1 + A22PE2+A23PD1+A24PD2
DTD1A = A31PE1 + A32PE2+A33PD1+A34PD2
DTD2A = A41PE1 + A42PE2+A43PD1+A44PD2
where:
DTE1A = Temperature difference between ambient and LED 1
DTE2A = Temperature difference between ambient and LED 2
DTD1A = Temperature difference between ambient and detector 1
DTD2A = Temperature difference between ambient and detector 2
PE1 = Power dissipation from LED 1;
PE2 = Power dissipation from LED 2;
PD1 = Power dissipation from detector 1;
PD2 = Power dissipation from detector 2

below the threshold during a
transient. A minimum LED cur-
rent of 10 mA provides adequate
margin over the maximum IFLH
of 5 mA to achieve 15 kV/µs
CMR.
CMR with the LED Off (CMRL)
A high CMR LED drive circuit
must keep the LED off
(VFVF(OFF)) during common
mode transients. For example,
during a -dVCM/dt transient in
Figure 31, the current flowing
through CLEDP also flows
through the RSAT and VSAT of
the logic gate. As long as the low
state voltage developed across
the logic gate is less than
VF(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 CLEDN must be
supplied by the LED, and it is

LED Drive Circuit 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
shown in Figure 29. The HCPL-
3150/315J improves CMR
performance by using a detector
IC with an optically transparent
Faraday shield, which diverts
the capacitively coupled current
away from the sensitive IC
circuitry. How ever, this shield
does not eliminate the capacitive
coupling between the LED and
optocoupler 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/µs CMR while minimizing
component complexity.
Techniques to keep the LED in
the proper state are discussed in
the next two sections.
not recommended for applica-
tions requiring ultra high CMRL
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.
Under Voltage Lockout Feature
The HCPL-3150/315J contains
an under voltage lockout (UVLO)
feature that is designed to
protect the IGBT under fault
conditions which cause the
HCPL-3150/315J supply voltage
(equivalent to the fully-charged
IGBT gate voltage) to drop below
a level necessary to keep the
IGBT in a low resistance state.
When the HCPL-3150/315J
output is in the high state and
the supply voltage drops below
the HCPL-3150/315J VUVLO-
threshold (9.5 <VUVLO- <12.0),
the optocoupler output will go
into the low state with a typical
delay, UVLO Turn Off Delay, of
0.6 µs. When the HCPL-3150/
315J output is in the low state
and the supply voltage rises
above the HCPL-3150/315J
VUVLO+ threshold
(11.0 < VUVLO+ < 13.5), the
optocoupler will go into the high
state (assuming LED is “ON”)
with a typical delay, UVLO
TURN On Delay, of 0.8 µs.
IPM Dead Time and Propagation
Delay Specifications
The HCPL-3150/315J includes a
Propagation Delay Difference
(PDD) specification intended to
help designers minimize “dead
time” in their power inverter
CMR with the LED On (CMRH)
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

to the low-voltage motor rails.
To minimize dead time in a
given design, the turn on of
LED2 should be delayed
(relative to the turn off of LED1)
so that under worst-case
conditions, transistor Q1 has
just turned off when transistor
Q2 turns on, as shown in Figure
34. The amount of delay
necessary to achieve this condi-
tions is equal to the maximum
value of the propagation delay
difference specification,
PDDMAX, which is specified to be
350 ns over the operating
temperature range of -40°C to
100°C.
Delaying the LED signal by the
maximum propagation delay
difference ensures that the
minimum dead time is zero, but
it does not tell a designer what
the maximum dead time will be.
The maximum dead time is
equivalent to the difference
between the maximum and
minimum propagation delay
difference specifications as
shown in Figure 35. The
maximum dead time for the
HCPL-3150/315J is 700 ns
(= 350 ns - (-350 ns)) over an
operating temperature range of
-40°C to 100°C.
Note that the propagation delays
used to calculate PDD and dead
time are taken at equal tempera-
tures and test conditions since
the optocouplers under
consideration are typically
mounted in close proximity to
each other and are switching
identical IGBTs.
