Description
The HCPL-3150 consists of a
GaAsP 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 applica-
tions. The high operating voltage
range of the output stage pro-
vides 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-3120 can be used to
drive a discrete power stage
which drives the IGBT gate.

Selecting the Gate Resistor
(Rg) to Minimize IGBT
Switching Losses.
Step 1: Calculate Rg Minimum
From the IOL Peak Specifica-
tion. The IGBT and Rg in Figure
26 can be analyzed as a simple
RC circuit with a voltage supplied
by the HCPL-3150.
Rg ≥ –(V–C–C–––I–O–VL–EP–EE–A-K–V–O–L–)–
= (–V–C–C–––I–O–VL–EP–EE–A-K–1––.7––V–)
= (–1––5–V0––.+6––A5––V––-–1–.–7––V–)
= 30.5 Ω
The VOL value of 2 V in the pre-
vious 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 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
Power Dissipation and
Increase Rg if Necessary. The
HCPL-3150 total power dissipa-
tion (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)
= ICC•(VCC - VEE)
+ ESW(RG, QG) •f
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 TA
max = 90°C:
PE = 16 mA•1.8 V•0.8 = 23 mW
PO = 4.25 mA•20 V
+ 4.0 µJ•20 kHz
= 85 mW + 80 mW
= 165 mW
> 154 mW (PO(MAX) @ 90°C
= 250 mW−20C•4.8 mW/C)
