Description
Features
The HCPL-315X consists of an 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
HCPL-3150 fig 24
Eliminating 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 HCPL3150/315J 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.)
To keep the IGBT firmly off, the HCPL-3150/315J has a
very low maximum VOL specification of 1.0 V. The HCPL3150/315J realizes this very low VOL by using a DMOS
transistor with 4 Ω (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 Ω. 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

Selecting the Gate Resistor (Rg) to Minimize IGBT Switching Losses.
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.

IOLPEAK
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):
PT = PE + PO
PE = IF • VF • Duty Cycle

PO = PO(BIAS) + PO (SWITCHING)

For the circuit in Figure 26 with IF (worst case) = 16 mA,
Rg = 30.5 Ω, Max Duty Cycle = 80%, Qg = 500 nC, f = 20
kHz and TAmax = 90°C:
= 30.5 Ω
The VOL value of 2 V in the pre­vious equation is a conservative value of VOL at the peak current of 0.6 A (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.

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).
From the thermal mode in Figure 28a the LED and detector IC junction temperatures can be expressed as:
Since PO for this case is greater than PO(MAX), Rg must be
increased to reduce the HCPL-3150 power dissipation.

For Qg = 500 nC, from Figure 27, a value of ESW = 3.45 µJ
gives a Rg = 41 Ω.
Thermal Model (HCPL-3150)
TJE = PE• 313°C/W + PD• 132°C/W + TA
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 θCA which
raises the case temperature TC accordingly. The value of
θCA depends on the conditions of the board design and
is, therefore, determined by the designer. The value of
θCA = 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
θCAvalue of 83°C/W.

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.
CMR with the LED On (CMRH)
Esw – ENERGY PER SWITCHING CYCLE – µJ
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 cur­rent 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
(VF ≤ VF(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 not recommended for applications
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 designs.
Dead time is the time period during which both the high
and low side power transistors (Q1 and Q2 in Figure 25)
are off. Any overlap in Q1 and Q2 conduction will result
in large currents flowing through the power devices
from the high- 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
condi­tions 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 tempera­tures and test
conditions since the optocouplers under consider­ation
are typically mounted in close proximity to each other
and are switching identical IGBTs.
