-xxxE denotes a lead-free product
Description
The ACPL-P302/W302 consists of a GaAsP LED optically
coupled to an integrated circuit with a power output
stage. These optocouplers are ideally suited for driving
power IGBTs and MOSFETs used in motor control invert-
er 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
small or medium power IGBTs.

Applications Information
Eliminating Negative IGBT Gate Drive
To keep the IGBT firmly off, the ACPL-P302/W302 has a
very low maximum VOL specification of 1.0 V. Minimizing
Rg and the lead inductance from the ACPL-P302/W302
to the IGBT gate and emitter (possibly by mounting the
ACPL-P302/W302 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 17. Care should
be taken with such a PC board design to avoid routing the
IGBT collector or emitter traces close to the ACPL-P302/
W302 input as this can result in unwanted coupling of
transient signals into the input of ACPL-P302/W302 and
degrade performance. (If the IGBT drain must be routed
near the ACPL-P302/W302 input, then the LED should be
reverse biased when in the off state, to prevent the tran-
sient signals coupled from the IGBT drain from turning on
the ACPL-P302/W302.
Selecting the Gate Resistor (Rg)
Step 1: Calculate Rg minimum from the IOL peak specifi-
cation. The IGBT and Rg in Figure 17 can be analyzed as
a simple RC circuit with a voltage supplied by the ACPL-
P302/W302.

= 57.5 Ω
The VOL value of 1 V in the previous equation is the VOL at
the peak current of 0.4A. (See Figure 4).
Step 2: Check the ACPL-P302/W302 power dissipation and
increase Rg if necessary. The ACPL-P302/W302 total power
dissipation (PT) is equal to the sum of the emitter power
(PE) and the output power (PO).

Switching Cycle.
PT =PE +PO
PE = IF u V F u DutyCycle
P O = P O(BIAS) + P O(SWITCHING) = ICC u V CC + E SW (Rg; Q g ) u f
= (I CCBIAS + K ICC u Q g u f) u VCC + E SW (Rg ; Q g ) u f
where KICC · Qg · f is the increase in ICC due to switching
and KICC is a constant of 0.001 mA/(nC*kHz). For the circuit
in Figure 17 with IF (worst case) = 10 mA, Rg = 57.5 :, Max
Duty Cycle = 80%, Qg = 100 nC, f = 20 kHz and TAMAX =
85°C:
PE = 10 mA u 1.8V u 0.8 = 14 mW
PO = (3 mA + (0.001 mA/nC u kHz) u 20 kHz u 100 nC) u 24V +
0.3 μJ u 20 kHz = 126 mW £ 250 mW ( P O(MAX) @85 °C)
The value of 3 mA for ICC in the previous equation is the
max. ICC over entire operating temperature range.
Since PO for this case is less than PO(MAX), Rg = 57.5 : is
alright for the power dissipation.
